Ajihei is one of the best Japanese restaurants in Princeton. It serves very fresh sushi, and is made to order right in front of you. Most of the seats are right in front of the sushi bar, giving a great view of your food while it is being made. The menu, however, is very limited, as sushi is pretty much the only food served at Ajihei. And it is very pricey too - for the same amount, you could probably go to a good restaurant in New York City. Ajihei is located in the basement of a building, so the location isn't great.
