Chaya is an excellent neighborhood Japanese restaurant. They recently just moved to a location right up the street, which allows for much more space for seating. (Before it had a smaller seating area and, due to the fact that it is so popular, was always crowded.)
I literally go here at least once a month, and I have never had bad service. The waitresses are always very friendly, attentive, and knowledgeable about the menu. There dumplings are great, and all the sushi is delicious. I cannot speak to their entrees, but their sushi is some of my favorite in Pittsburgh.
