This place is pretty much packed all the time. I have tried going on tuesday nights, wednesday nights - you can get a table, usually, but it's still really busy. I avoid it completely on friday & saturday nights now. People spend 2 hours at the bar waiting for their table and by the time dinner comes they're loaded. It's something you only want to deal with if you're drunk yourself.
The sushi is incredibly hit and miss here. I've been there and had tuna sashimi that was just perfect, and the next time I go back it's so awful I can't eat it. So I don't go here for sushi anymore.
I like the teppanyaki tables where they cook in front of you. I'm a huge fan of the sea bass. The kobe beef is also fantastic... when I can afford it! lol I think the teppanyaki food is very well done and that's what I get when I come here.
Other great dishes are the kobe burger, and the wasabi shrimp cocktail.
