Let Us Feed Your People

Burger trays, fry boxes, shake platters — for 10 or 200

We've catered office lunches where 40 engineers demolished 80 burgers in 20 minutes. We've done birthday parties for eight-year-olds who ate more than their parents. One time we catered a wedding — the couple met at our San Bruno location and wanted burgers instead of filet mignon. Smart people.

Catering from Big Mouth is exactly what you'd get if you walked into our restaurant, except we bring it to you. Same beef, same flame grill, same hand-cut fries. Nothing changes just because there's a bigger order.

What's Included

Every catering order comes with plates, napkins, utensils, condiments (ketchup, mustard, our house sauce), and a toppings setup — lettuce, tomato, onion, pickles. We bring serving trays and we'll set everything up if you want. Cleanup is on you, but honestly, there's never much left.

Add-Ons

Shake Platters

Mitchell's ice cream shakes in vanilla, chocolate, or strawberry. Served in individual cups. $6 per shake, minimum 10.

How to Order

Call either location directly. We need at least 48 hours notice for orders under 50 people, and one week for anything bigger. We'll work out the details on the phone — menu choices, dietary restrictions, setup time, that kind of thing.

San Bruno: (650) 871-5237

Mission SF: (415) 282-6599

We deliver catering orders within 15 miles of either location. Delivery fee depends on distance — usually $25-50. Or you can pick up and save.

Past Events

We've catered for tech companies in SOMA, schools in the Sunset, family reunions in Pacifica, and a retirement party for a guy who'd been eating at our San Bruno spot every Friday since 2003. Whatever the occasion, the food is the same — real burgers made right, just more of them.
