20 Questions to Ask Before You Hire a Coffee Cart
What to ask, what a professional answer sounds like, and where to look closer.
The barrier to entry for a coffee cart business is low. A cart can be rented, a website can be built in a weekend, and neither one tells you whether the person behind them has ever run service for three hundred guests.
These are the questions that surface the difference. Most of them take a vendor about ten seconds to answer if they know their business, and considerably longer if they do not.
Start here
The Coffee Itself
Where do you source your beans, and how recently were they roasted?
Coffee is at its best within a few weeks of the roast date. This question separates operators with a real roaster relationship from those buying whatever is on the shelf.
Good answer
Names the roaster and describes how often they take delivery.
Look closer
"We use a local roaster" with no name attached, and no mention of roast dates.
How we answer this
We are partnered with Ready Set Coffee, a Cleveland roaster. If you want to know exactly what we will be pouring the week of your event, ask us and we will tell you.
Do you grind fresh for each drink?
Ground coffee goes flat quickly. Pre-grinding is the single fastest way to make good beans taste ordinary, and it is common among operators optimizing for speed over quality.
Good answer
Grinds to order, and can explain why it matters.
Look closer
Pre-ground, or vague about when the grinding happens.
Do you filter your water?
A drink is almost entirely water. Municipal water varies a lot across Greater Cleveland, and unfiltered water shows up in the cup as a flat or metallic finish.
Good answer
Filters on site, or brings their own water.
Look closer
Has not thought about it.
Are your syrups house-made or bottled, and what flavors do you carry?
Flavored syrup is where cost-cutting hides. It rarely comes up in a tasting, and it is the difference between a vanilla latte that tastes like vanilla and one that tastes like candy.
Good answer
A specific answer about what they use and why, and a flavor list they can send you.
Look closer
Cannot say what brand or type they use.
How we answer this
We favor DaVinci Gourmet all-natural flavors and use Torani on occasion. We are happy to walk you through the full flavor list before you book — the current lineup is on our menu.
What milks do you offer?
Oat, almond, and lactose-free are no longer special requests. A vendor who charges extra for them, or carries only one, will create a line of disappointed guests.
Good answer
Multiple non-dairy options carried as standard.
Look closer
One non-dairy option, or an upcharge per drink.
What grade of matcha do you use, and how do you make your cold brew?
Both are easy to fake. Culinary-grade matcha in a latte tastes bitter and looks dull, and "cold brew" is often just iced drip coffee.
Good answer
Names the matcha grade, and describes a real steeping process for the cold brew.
Look closer
Treats the two as interchangeable with anything else on the menu.
The people
Skill and Track Record
Do you use manual espresso machines or superautomatics?
A superautomatic pushes a button and dispenses. A manual machine requires a trained barista. Neither is disqualifying, but it tells you what kind of operation you are hiring and what the drinks will taste like.
Good answer
A direct answer either way, with a reason behind the choice.
Look closer
Evasive, or does not seem to know the difference.
How we answer this
Both, and we choose per event. When we are serving a large group in a short window, we may run an automated machine to pull shots while we steam on the manual machine, which keeps the line moving. What comes to your event depends on guest count, service window, and menu. We favor Nuova Simonelli and Jura.
Who is actually working my event?
This is one of the sharpest filters on the list. Some operators book the job and then scramble to staff it, and the person who shows up has never touched that machine before.
Good answer
Trained baristas who work with the company regularly, and a named lead for your event.
Look closer
Vague about who will be there, or staffing pulled fresh from a gig app for every booking.
How we answer this
We staff local baristas who work with us regularly and know our equipment, and every event gets one assigned team lead who is responsible for it start to finish. You will know who that is before the day.
Do your baristas do latte art, and can you print a logo on the drinks?
Latte art is a fair proxy for training — it is hard to fake and takes practice. Printed logos need specific equipment, so the question separates vendors who have it from those who will say yes and figure it out later.
Good answer
Yes to the art, and a clear answer on printing including lead time and any cost.
Look closer
"We can probably do that" with no detail on equipment or timing.
How we answer this
We staff local baristas — most can pour a basic heart, and several go well beyond that. Printed logos on drinks are included at no extra charge when you ask for them. We need your artwork about three weeks ahead of the event.
Can I taste your coffee before booking?
You are about to serve this to every guest at your event. A vendor confident in their coffee will want you to try it.
Good answer
Offers a tasting, or a way to try the coffee before you commit.
Look closer
Deflects, or has no way for you to taste anything.
How long have you been doing this, and what is the largest event you have served?
Volume is where inexperience becomes visible. A cart that runs beautifully for forty guests can collapse at four hundred, and the failure happens in front of everyone.
Good answer
A specific number of guests and a description of how they staffed it.
Look closer
Answers about years in business but cannot describe a large event.
What venues and clients have you worked with?
Venue names are the hardest thing on this list to fake. A vendor who has worked your venue already knows its load-in, its power, and its coordinator.
Good answer
Names venues and organizations without hesitating.
Look closer
Speaks only in general terms about "lots of corporate clients."
The setup
The Cart and the Look
How big is your cart, and what space and power do you need?
Your venue coordinator will ask you this before they ask anything else. A vendor who cannot answer it has not done many events.
Good answer
A specific footprint, the clearance needed for the barista and a guest line, and exact power requirements.
Look closer
"It fits anywhere."
How we answer this
We run 4-foot and 5-foot carts, and when a doorway or corridor will not take either one, we can tear down and rebuild on site. What we do need is ramp or elevator access — our equipment moves on dollies, so stairs are the one thing that stops us. Power is standard 110V outlets with no 220 required, and the amp draw runs roughly 20 to 36 depending on the size of the event. We do not need a water hookup. We put all of this in writing to your venue ahead of the day so nothing surprises anyone at load-in.
What setup options do you have?
One room is not another. A vendor with a single configuration will make your space work for their cart instead of the other way around.
Good answer
Multiple configurations — single cart, multiple carts for larger crowds, indoor, outdoor, tented — and an explanation of how staffing and speed change with each.
Look closer
One setup, and no plan for a room that does not suit it.
Can you match our theme or branding?
This is where "yes, we can do anything" costs you money later. Custom work has real lead times and real costs, and both should be on the table before you sign.
Good answer
Specifics — cart styling, signage, custom drink names, branded cups, color coordination — plus lead times and any additional cost.
Look closer
"Sure, whatever you want," with no detail on timing or price.
The fine print
Service, Insurance, and Terms
What is included, and what costs extra?
This is where a low quote becomes an expensive invoice. Ask specifically about matcha, seasonal drinks, printed logos, branded cups, extra flavors, travel, setup and breakdown time, and overtime.
Good answer
A clear list of what is included and what is not, with most of it already in the base price.
Look closer
"We will work it out" — followed by a revised invoice.
How we answer this
Matcha, seasonal drinks like pumpkin spice, decaf, hot cocoa, and hot teas are all in the base package — we do not upcharge for any of them, and printed logos are included on request. Two things sit outside the base price. A travel fee runs from $15 to $140 per barista depending on distance, and time beyond the standard service window is billed hourly. Standard service is an hour and a half to two hours; the hourly rate past that scales with the size of your event.
How many drinks per hour can you serve, and how many baristas come with the cart?
Throughput is the difference between a coffee cart and a coffee line. Multiply your guest count by the service window and see whether the math works before you book.
Good answer
A drinks-per-hour figure tied to a staffing level, and a recommendation for your specific guest count.
Look closer
A number with no staffing behind it, or no number at all.
How we answer this
One barista covers events up to about 50 guests. Depending on how many baristas we staff, we serve somewhere between 50 and 100 drinks an hour. Tell us your guest count and your service window and we will tell you honestly what it takes to get everyone through the line.
Are you insured, and can you provide a certificate naming our venue?
Most venues require a certificate of insurance naming them as additional insured. A vendor who hesitates here either is not carrying coverage or has never been asked, and both are a problem days before your event.
Good answer
Yes without hesitation, and they ask who to name on the certificate.
Look closer
Any hesitation at all, or a promise to "look into it."
How we answer this
We carry liability coverage and can provide a certificate of insurance. Send us your venue details and we will get the certificate over to their coordinator.
What happens if equipment fails?
Espresso machines fail. Experienced operators plan for it; new ones find out during your event.
Good answer
Backup equipment on the truck, or a described contingency plan.
Look closer
Has never considered it.
What are your deposit, cancellation, and overtime terms?
Everything should be in writing before money changes hands. A vendor without a real contract is a vendor without a real business.
Good answer
A written contract with the terms spelled out, sent before you pay anything.
Look closer
A verbal agreement, or terms that appear only after the deposit clears.
How we answer this
A 50% deposit confirms your date, and until it is received the date stays open — we will tell you plainly if someone else is asking about it. Cancel at least 10 days out and the deposit comes back minus a $35 administrative fee. Between 10 days and 72 hours, half the deposit is forfeited; inside 72 hours, the full deposit is. The balance is due the day we serve. If you ask us to stay past the agreed end time, that is arranged and paid at the time of the extension. All of it is in writing before you pay anything.
Before you call anyone
Four Questions That Aren't About the Vendor
These are yours to answer, not theirs. They vary by venue, by city, and by the kind of event you are hosting — and they can undo a booking that was otherwise perfect.
Ask your venue whether outside coffee vendors are allowed at all.
Many venues hold exclusive catering contracts or maintain an approved vendor list, and a coffee cart that has not been cleared can be turned away at the door. This is the question that comes before all the others, and it is on you to ask, not the vendor.
Ask your venue what they require from a vendor in writing.
Most will want a certificate of insurance naming them as additional insured. Some also set load-in windows, freight elevator reservations, and parking arrangements. Get the list early and pass it to your vendor.
Check with your local health department about your specific event.
Requirements for mobile food and beverage service vary by municipality and by event type, and Greater Cleveland is no exception — what applies in one city may not apply in the next one over, and a private indoor event may be treated differently from a public outdoor one. Confirm what applies to your event directly with the health department that covers your venue, and ask your vendor how they have handled it elsewhere.
Ask whether the vendor has worked your venue or your city before.
A vendor who has been there already knows the loading dock, the power situation, and the coordinator by name. It is not a requirement, but it removes a lot of variables on the day.

Six Things Worth a Second Look
- A price well below every other quote for the same guest count
- Hesitation about providing a certificate of insurance once you name the venue
- No specific venues or clients they can point to
- Vague on drinks per hour and how many baristas are included
- No written contract, deposit terms, or cancellation policy
- Slow or scattered communication before you have even paid
