Love this place. Chaya is extremely good, decent prices and an hidden gem in Squirrel Hill. This is my default go-to place for sushi. Even better these days since they moved - however the secret is getting out and there is sometimes a short wait to get in.
The waif-staff is always very nice. Orders come out at typical speed for a sushi bar. You'll wait a little longer when they are busy.
Rolls are a perfect size - not to big, not too small. Sashimi is a good sized too.
Japanese food is quite excellent as well. I always have a hard time decided what to get here.
My only complain with Chaya has been with their ventilation systems lately. You don't notice it too much while you are there, but when you leave you smell like you have been working their all night. They need to get that looked at!
