I have been to sudachi only twice, but I plan to go back all the time. The food is really good, especially for the price. Probably not the best sushi in SF, but it is delicious. But what this place really did to earn my 5 star rating is that the entire dining experience is awesome! It's really good for sake bombing with a group of people... the drinks are really cheap (ONLY $5 PITCHERS) and the servers and chefs will drink with you! I had so much fun at this place and the later in the evening it got, the more of a party it became. I felt kind of bad for the people that worked there because they could hardly get through the crowd to serve food on a thursday night because of the dollar sakes. basically... if you want to have a great time and drink and eat sushi, this is the place for you! Only problem I had was on thursday it was a little too crowded and they ran out of pitchers, but I think we were all too drunk to care!
Pros: really cheap drink specials and awesome service/atmosphere
Cons: thursdays are too busy and it was really loud
