John's is one of my favorite restaurants in Pittsburgh. The menu is enormous and I've yet to encounter a single miss, from Americanized standbys (General Tso's) to dishes that would be more at home in a back-alley restaurant in Hong Kong. The sushi bears mention for its beauty alone--I don't know where the sushi chef was trained, but he's an artist.
John himself is one of the nicest and most gracious restaurateurs I've ever had the pleasure of meeting. He will honor any and all special requests, recommend new things, and even bring his regular customers new experiments from the kitchen to try (on the house). If you become a regular customer and get to know John, you're sure to get something new and delicious every time you come in!
5/5, Recommended highly.
