The Sesame Inn is probably one of the most consistently delicious Chinese/Asian restaurants in the North Hills, if not Pittsburgh. Service is generally very attentive, and the food, while not remarkably different from cuisine elsewhere, is probably better tasting than almost any comparable restaurant in the area.
They also have a decent selection of sushi. I've had better elsewhere, and I don't necessarily associate the Sesame Inn with sushi, but it's certainly not bad.
In short, I haven't left the Sesame Inn unsatisfied. It is basically my go-to Chinese restaurant while in the North Hills, and it beats out many in the city of Pittsburgh as well.
