Everything else gets planned. The coffee just appears. We think the smallest thing in the room is exactly the thing worth measuring.
Every RATIO morning opens the same way. The barista weighs the dose, pulls a shot, times it, tastes it, and adjusts, all in the open where people can see it. Temperature and humidity shift every day, so the numbers shift with them.
The day's figures go on a card on the bar. Origin, roast age, dose, yield, time, ratio. It takes a quarter of an hour, and it is the whole point.
Occasions
One morning, one afternoon, one long evening. A complete specialty bar and a barista who stays for the whole thing. Set up, poured to order, and cleared away without anyone noticing the work.
The same standard, week after week. A fixed morning on a fixed schedule, run the same way every time, so it stops being an event and becomes something people plan around.

RATIO serves the city of Chicago and the Chicago suburbs. We add a travel charge based on mileage and distance.
Any number. Whether it's a small gathering or a large event, tell us your guest count and we'll plan the service around it.
Yes. Weddings are one of the things we do best. Specialty coffee and espresso feel right at cocktail hour, dessert, and the late night send off, and we handle everything from setup to breakdown so the couple never has to think about it. We also take last minute weddings, even the day before. See our wedding coffee catering page for the full offering.
Yes. Baby showers, birthdays, engagement parties, graduations, retirement celebrations, anywhere your people are gathering. See celebrations & showers for menu ideas and setups for smaller events.
Absolutely. We do launches, offsites, and conferences, and we also run recurring weekly or monthly office coffee mornings for Chicago companies. See our corporate coffee catering page for details.
Matcha latte leads the menu, alongside espresso, americano, cappuccino, mocha, and lattes in Spanish, pistachio, and caramel. It's a deliberately short list, because a short menu is what lets every cup come out the same. We don't serve decaf or alcohol.
Yes. Whole, oat, almond, and lactose free milks are on the cart at every event, and every drink on the menu can be made with them. Matcha is what most guests reach for when they want something other than coffee.
The cart is 4 feet wide, and our barista needs open space around it to move freely. We need a standard power outlet near the cart, since we don't bring our own power. Water is on us. Outdoor setups need a level surface. We need access to your space 75 minutes before the event starts so everything is ready on time.
The host or event owner pays for the service, and guests never pay for a drink. No tipping is expected.
Yes. Custom touches aren't part of our standard setup right now, but you can request anything you have in mind and we'll price it for you.
Yes. RATIO is fully insured, and we can provide a certificate of insurance for any venue that asks for one.
