It's interesting that one of the most crowded restaurants in the South Side (possibly, all of Pittsburgh?) has such bad ratings on Yelp. I think Yelpers have it right in the case. Nakama totally did not live up to the hype for me. I had the hibachi and it was just mediocre. The chef / entertainer wasn't even that good - no cool tricks and he didn't even try throwing food in my mouth. The place was so loud that there is no way you can have a decent conversation if you come with a group of people. And, I swear they celebrated 10 birthdays during the hour we were dining there. They have this irritating gong that they bring out. You can't hear the guy next to you, but you will hear every birthday dinner that night.
A bunch of my co-workers like Nakama's sushi bar, so when I get a chance to try it, I'll update my review. Until then, I'm not quickly planning my next Nakama outing.
