What Diners Say

★★★★ Jamie Chan 3 weeks ago

Easy self seating on a Saturday afternoon for two, cocktails are solid but at market rate for this area. My matcha martini was well made and those duck fat fries were damn good! Brussel sprouts were as expected.... lots of standard bar fare and happy hour prices. Fast service, we would definitely g...

★★★★ "I stumbled into this restaurant without doing much research—honestly, the name had me expecting some kind of fermented-food theme, which made the actual menu a funny surprise. The atmosphere is airy and inviting, and the staff couldn’t have been warmer or more attentive.

★★★★★ "Beautiful bar/restaurant tucked away in San Francisco’s Japantown. Went here on a Friday night after the Warriors game with some friends. Beautiful location. Quiet, relaxed environment.

★★★★★ "They had an interesting menu. The atmosphere in there was really nice and the decor was fitting. Service was quick and we weren’t rushed at all after finishing our food. We stayed and talked for a good amount of time and requested the check when we were ready.

★★★★ "Came here for happy hour, $2 oyster was great. We had four servings, the oysters were fresh. Only had two that tasted funny, but overall is great, no sand, good size. Oysters were from Washington, still prefer eastern oysters that come with a bit of sweetness.
