As an expatriate of Pittsburgh, Sushi Tomo has been a former weekly haunt of mine. I think for sushi it is an excellent value and has a good sushi bar.
I have posted the main chef's photo (a little dated), but I thought he was a good sushi chef and decent conversationalist if you sit at the bar. I think most of creative sushi is well done.
The seating is a little dated, but has always been clean, and the service has been fine. It took no time to become a regular and become recognized easily for comps and other good service.
