Came here last night. The place is pretty well lit, so if you're looking for a low-light romantic atmosphere, then not so much. But it's still a very nice casual space. The staff are friendly and courteous.
I had the rainbow roll and an eel roll, both very good, as well as the ika nigiri (squid). She had the dragon roll and a salmon roll as well as the salmon nigiri, which were quite good as well.
Overall, I would say this is one of the better places to get sushi in Pittsburgh. The items were fresh and delicious. Pretty fast service even on a relatively busy night. Atmosphere, casual.
