I've been here a few times and had a decent time. Once I had a seat at the bar and was fed free samples of Japanese beer and sake until I was fairly buzzed. Another time, I had terrible greasy food and awful carpaccio and swore I'd never go back.
Well, I went back again because it has such a huge reputation and the line-up was non-existent, and the food was waaaaaay better. I had the calmari, stewed pork, bibimbap, takoyaki and several kinds of sake. The service was forgetful but as always cheery like crazy. It got a bit too loud but that's what it's all about. Nice decor and has a hidden unmarked door by the crummy parking lot in front of a convenience store. The patio looks nice and private.
