If you know what to expect, don't complain.
OK, it's Americanized sushi. But that's like its own type of cuisine now, so get over it. Don't expect a great sashimi creation, just come and order the rolls that sound like the most fun (a Tootsie Roll? no, it's not from Japan. duh.). Come at happy hour and they're pretty cheap.
It's a fun atmosphere, so expect a hip crowd. Waitresses who use their looks to make up for being bad servers. (Who cares?) A young, fun crowd with good drinks and good Americanized sushi.
The Yelp reviews on this place are pretty mixed. I'm guessing it's just the divide between people who knew what to expect on the one hand, and people who expected something different on the other.
