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.

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.
