Satto is the latest entry in the thai+sushi format. It's just down the street from the Engineer's Bookstore.
The sushi combination lunch comes in several variations. I had the shrimp tempura edition. The dish was surprisingly large and quite good. The sushi and sashimi were of very high quality; I had all the good flavor of the fish without any trace of stale fishiness. The tempura was very fresh and refreshingly crunch. You can see why tempura and sushi are such a popular combo.
