Good burger and they have rootbeer floats and shakes! It was better than expected, if you know the location, it's not known for its American food. It was a nice place to sit and chat and everyone was really friendly! I'll be back next time I'm in San Mateo.

One of the best burgers I've ever had and I'm a picky eater. Was so juicy and cooked perfectly to my request. Fries were tasty too. Far from my house but I'll definitely come back.

July 2025:
Stopped by for lunch on a Sunday and liked the old diner feeling.

Ordered an avocado 🥑 burger with French 🍟 fries. The burger was nice and thick. It came with onions, lettuce, tomato, mustard and mayonnaise. I really enjoyed the burger. I'd come back again.

The French fries were meaty. Very tasty 😋.

Thank you for a delicious burger.

One of the best burger shops in the Bay with many locations. They have reasonable prices, not to mention their delicious milkshakes which are big enough to share as they fill up two containers. Their bacon burger and pineapple teriyaki burger are my favorites.

The diner-like interior has booth seating and a good corner window seat. They have back patio seating and the restroom is oddly located through the kitchen.

The staff are friendly and service is quick!

Excellent burgers, onion rings, garlic fries. Everything tastes high quality and I love the old school feel.

This place is a peninsula staple. I've been going there since I was a teen and the burgers never stopped being good. Also the fresh garlic on the fries are better than you can get at the ballpark.

Delicious old fashioned burgers.

These are the best burgers, hands down! They're actually made with ground steak.
