BIG MOUTHSSF

The Menu

Everything's made to order. Pick your bread, pick your spread. Comes with fries, beans, or slaw. Check our FAQ for allergen details and where we source every ingredient.

Burgers

Flame-grilled cheeseburger with fresh lettuce and tomato

Half-pound prime ground chuck, hand-patty, flame-grilled. French roll. Swap for GF bun — just ask.

The Big Mouth

The one that started everything. Good beef, good bun, good ratio. You already know if you've been here before.

Bestseller

The Hangover

Fried egg, thick-cut bacon, chipotle mayo. People eat this at all hours. We stopped judging a long time ago.

Staff Pick

Warriors Burger

Pastrami stacked on the patty with our BBQ spread. Named during the 2015 championship run. Pastrami's from a local deli, not packaged.

Fan Favorite

Giants Burger

Bacon, cheddar, BBQ sauce, onion rings on top. Big enough to justify the name. Not a delicate eating experience.

Hawaiian Burger

Grilled pineapple ring, teriyaki sauce, Swiss. Some people think pineapple on a burger is wrong. Those people haven't tried this one.

Mushroom Swiss

Sauteed mushrooms, Swiss cheese, garlic aioli. Quieter than the Warriors but consistently in our top five sellers.

The Californian

Beyond Meat patty, avocado, sprouts, vegan mayo. GF bun available. Outsells three beef options. We were surprised too.

Vegan

Garden Burger

House-made veggie patty, grilled. Standard toppings. Straightforward, no pretension.

Vegetarian

Small Mouth

Quarter pound. Same quality, slightly less ambitious portion. Same beef, same grill. Just... smaller mouth.

Turkey Burger

Ground turkey, grilled. Lighter option that regulars keep reordering, which we take as a compliment.

Salmon Burger

Wild-caught salmon patty. A little unexpected on a burger menu, sure. But it works. SSF regulars turned us onto this one.

Sandwiches & More

Crispy fried chicken sandwich on a fresh bun

Served with fries, baked beans, or coleslaw. Your call.

Fried Chicken Sandwich

Crispy fried chicken breast on a French roll. Ask for extra pickles — trust us. Might be the sleeper hit of the whole menu.

Sleeper Hit

The Texan

Slow-roasted pork loin, southern BBQ sauce, coleslaw on a bun. Extra slaw on the side adds a crunch you didn't know you needed.

Fish & Chips

Beer-battered cod, fries. We know it's a burger place. But we sell enough of these that we're not taking it off.

Grilled Cheese

Sometimes you just want melted cheese on bread. We get it. This is that, done well.

Sides

Golden french fries and crispy onion rings

Full-size orders fill an entire large clamshell. Easily shareable between two.

French Fries

Golden, crispy, generous. Full or half size.

Garlic Fries

Tossed with roasted garlic and parsley. Strong garlic presence — plan your evening accordingly.

Popular

Sweet Potato Fries

Crispy outside, soft inside. Popular with the GF crowd and honestly everyone else too.

Beer-Battered Onion Rings

Crunchy in a way that survives delivery. People say they're the best on the peninsula. We just make them the same way every time.

Legendary

Caesar Salad

Full size — big enough to be a meal. Ask for dressing on the side unless you like it heavy.

Greek Salad

Feta, olives, cucumbers, tomato, red onion. Bigger than it needs to be, in a good way.

Shakes & Drinks

Thick chocolate milkshake with whipped cream

Shakes made with Mitchell's Ice Cream — the San Jose Ave institution since 1953.

Mitchell's Shake

Chocolate, strawberry, vanilla bean, banana. One size — and the size is already ridiculous. Thick enough you'll need a spoon first.

Must-Try

Float

Mitchell's ice cream with root beer or cream soda. Old-fashioned in the best possible way.

Fresh Lemonade

Squeezed in-house. Not from a mix, not from a gun.

A few things worth knowing: We hand-patty every burger to order — cook times vary during peak hours, but it's always fresh off the grill. Pet-friendly outdoor seating at both locations. GF buns and vegan patties on any burger. Prices may differ slightly between locations and delivery apps. For the most accurate pricing, call us or walk in. You can also order delivery through DoorDash, UberEats, or Grubhub.

Hungry Yet?

Walk-ins welcome at both locations. No reservations needed.
