Not many place in Pittsburgh deliver sushi, not only is Osaka won of them, it's some of the best in town. If you decide to get out the house their service is excellent as well. It's true about the owner, he will always make sure everything is alright personally.
The fresh sushi isn't the only great thing in Osaka, the all white meat General Tso is additively good. From the lo mien to the egg rolls almost anything on the menu is top quality, you really can't go wrong. I've eaten there dozens of times and plan on going again tomorrow.
