Banzai offers many types of sushi, all of good quality, all expertly prepared, but it really gets on a roll when it contemplates sushi-roll possibilities. The restaurant offers more than a hundred types, divided into nine categories: no fish on the outside; seaweed outside (traditional roll style); crunchy tempura batter on the outside; fish on the outside; eel on the outside; NITRO (those would be the spicy ones); avocado on the outside; whole roll deep-fried; and, when available, harder-to-get sea urchin and bonito. Pick a combination of ingredients -- say, shrimp, asparagus, avocado, gourd and mayo -- and a style (do you want that deep-fried, the shrimp wrapped around it all, or the avocado on the outside?), then let the good times, and the good tastes, roll.
