I can't read this board w/o posting on a great new sushi house in princeton called ajihei.
it is the only decent -- and authentically japanese -- sushi place in town...when i was there half the customers were japanese (some of them apparently east asian professors at the univeristy). the sushi rice, the fish, and the atmosphere all create the best i have yet to see in princeton. you'll find it just off nassau street (the main drag) on chambers st., near the old twist rojo. byob, i believe.
they even have toro!
