Chaya is simply amazing. It's a little hole in the wall place in Squirrel Hill that doesn't immediately grab your attention. It's extremely small inside so make sure you go in small groups. They are also very picky about your entire group being there before you are seated.
The service is quick and friendly and the waitresses will make suggestions for you if for some reason you can't decide between two rolls that look equally amazing :) The rolls are all very consistently good and the fish is always extremely fresh. The menu is very traditional - there are a few rolls that have a bunch of different ingredients but it's not a "fusion-sushi" type of place that seems to be getting popular. The sushi is very affordable, especially for the quality. Now if only I still lived right around the corner...
