Beyond expectations
Fluffy, Generously Seeded Buns
The burger buns at Big Mouth Burgers are noticeably soft and fluffy, with signature touches like sesame-seed-covered buns that signal care in the details of how each burger is assembled and presented.
Milkshakes Made with Mitchell's Ice Cream
Rather than using a generic ice cream base, the milkshakes are crafted with Mitchell's — a locally beloved San Francisco creamery — giving the shakes a distinctly familiar, high-quality flavour that loyal customers return for specifically.
Portion Sizes That Genuinely Satisfy
Burgers are sized generously enough that customers have found themselves unable to finish them — a reliable signal that the kitchen isn't cutting corners on what lands on your tray.
An Owner Who Shows Up
The owner has been spotted on the floor greeting guests in person, creating a welcoming atmosphere that feels personal rather than corporate — the kind of touch that turns a one-time visit into a habit.
A Menu That Rewards Exploration
Beyond burgers, the kitchen turns out items like cheesesteaks and onion rings that regulars speak of with genuine enthusiasm — suggesting the care put into the core menu extends across everything on offer.
Consistently Friendly Staff
Multiple visitors across different visits and years have independently noted the warmth of the staff, pointing to a team culture of hospitality that holds up over time rather than being a one-off impression.
A Clean, Comfortable Space
The dining area is described as immaculate and tidy, with a cosy, small-scale atmosphere that makes the experience feel considered — not just a place to grab food and leave.
Flavour That Matches the Presentation
Customers have noted that burgers look appealing and then actually deliver on that promise in taste — a consistency between appearance and flavour that builds confidence and removes the disappointment of style over substance.
Tips for your first visit
Make the most of your visit
Order fries well-done
Ask the staff to make your fries well-done so they stay crispy, especially if you're ordering takeout or delivery.
Try the onion rings
If you're not sure about the fries, the onion rings are a solid alternative worth ordering.
Don't skip the milkshakes
The milkshakes are made with Mitchell's ice cream, making them a standout item worth adding to your order.
Ask about mango shakes
Mango milkshakes appear occasionally as a special offering, so it's worth asking the staff if they have it available.
Go hungry for burgers
Portions are quite large — the signature burger in particular is a generous, filling meal on its own.
Explore beyond the burgers
The menu goes further than burgers, with sandwiches and a cheese steak that regulars speak highly of.
