Food is excellent and authentic. Mama San is the sweetest and the service is beyond exceptional! Definitely listing this as one of our favorite places to go when in town.

This is one of my all time favorite restaurants. Food is excellent and authentic. Mama San is the sweetest and the service is beyond exceptional! Great selection of food (not just sushi). Absolute gem of a Japanese restaurant. Excellent service, delicious food.

Such a wonderful place. The food is tasty, the atmosphere is sublime, the service and people running the restaurant are lovely. Don't even think twice, just go. You absolutely will not regret your choice. Mama San is reminded me of my favorite grandmother in the best possible way.

Great food... Great service with lots of personality. If you like saba (mackerel) nigiri... It's a must try! Traditional.

Excellent food. Charming, cozy place, family-run. Will definitely be back. Unagi Don with sashimi, gyoza, and cheesecake were all terrific. Cheesecake is very unique! Has an eggy almost flan-like texture, light and delicious. Great little gem of a place.

Absolute gem. Mamasan is the best! She is the sweetest, most delightful person and takes every order. this place brings me back to my trip to Japan, which I cherish.

The most authentic Japanese meal I’ve had in the Bay Area. This is inclusive of some of the top rated places in SF. Mama-san is a gem! The food is also high quality, maybe low presentation, but very fresh and tasty!

A nice family run spot, great food and incredible service. The family that served us was so sweet.
