I have been going to this small underground bar for the past several years because of its cool intimate atmosphere and wide array of sake, but NO MORE- WORST SERVICE EVER!!!!! We were constantly searching for waitstaff to ask for more drinks and waited twenty minutes for the check. Accordingly we did not leave more than 15% after which our server came over and asked about the tip. After indicating that we didn't really feel like discussing it, he told us that "15% is unacceptable" He then followed us to the door and asked if we had forgotten to leave a cash tip- REALLY? We had to explain to him that bad service= bad tip. If you don't like being bullied into leaving a big tip, you might want to have your sake elsewhere!
