Explore celebrations →Why RATIO
Most catering coffee is a tank of drip brewed ahead of time. Ours is specialty coffee, made per drink, with the same discipline we'd apply behind the bar at a top coffee shop.
Every shot is 18 g in, 36 g out, in 25 to 30 seconds. Not guessed, not eyeballed. The numbers go on a card on the bar for anyone who cares to see.
Freshly roasted espresso beans, never bulk commodity coffee. The kind of coffee guests would drive across town for.
The bar becomes a gathering point. People talk to the barista, wait a minute, and share a small ritual. That's what they remember.
Where We Serve
The city and the Chicago suburbs. We add a travel charge based on mileage and distance.
Coffee Catering FAQ
Coffee catering is a mobile bar service that brings specialty coffee and espresso to your event, with the equipment, the beans, the barista, the milk, the cups, and the cleanup all handled by an outside team. RATIO's version is a full specialty bar: freshly roasted beans, well trained and certified baristas, and a menu that reads like your favorite coffee shop, set up wherever you need it.
Send your event details through the booking form, by email, or by phone, and we'll reply with a tailored quote in less than one business day. The host covers the service, so guests never pay for a drink.
