If line ups are any gauge, this is the most popular sushi place on Earth. It's partly because the sushi is good, and partly because the sushi is inexpensive. There are two floors of seats, most of which are usually full, especially anytime around lunch, and after 6pm. Try and get yourself in the section by the window on the 2nd floor. Definitely the nicest part of the restaurant.
The menu is standard sushi fare, with a variety of maki, sashimi, bento boxes, etc. Something I usually like to do is team up with a friend and either get 1 maki combo and and 1 sashimi combo, or perhaps 2 different maki combos and trade sushi.
