I respectfully disagree on PJ's, Alex. The portions are tiny, and every time I've been there the BBQ has been dry and largely tasteless.

The sushi place is actually called Sushi Na and is excellent. It's a tiny little place in a shopping strip just off Route 9.

Also good is Kasa, which is in the Hannaford Plaza on Clifton Country Road. The chicken box lunch is amazing (miso soup, rice, chix teriyaki, four seafood shumai, four pieces of tempura--two of which are shrimp--and a california roll, all for $8.95).
