Banzai has been there since I was a child, I am 26 now. If the food was bad, then it would have been long gone like the countless others who competed with them. The infamous Hong Kong eventually went out of business, and they were considered the best, because they were.
As of right now, the Da Ming Express, formerly known as the Rice King, is the only competition around. The only other sushi competition as of right now is Buffet City. In comparison, your better off at Banzai, hands down. Although Buffet City has great weekend meals, such as seafood!
The sushi bar is excellent, and for the prices you got to love it. The other sushi bars who popped up(then out), had insane prices for so-so sushi, such as Cafe Trang, which disappeared real quick. In Salt Lake, there is much more competition, and way bigger places. But in West Valley, Banzai is #1, especially in Sushi.
Banzai gives 50% off if you eat inside the restaurant. If you get a California roll, that is 2 dollars for 7 pieces. Beat that at mcdonalds or betos.
The sushi chefs are extremely cool, and you can enjoy your sushi as though you were drinking with your bar keep.
They also do delivery to my house, which is also very convenient, although I just drive there and get the 10% off take out prices.
Over all the food is very good. The only thing Da Ming does better is the soup, like won-ton. As for their prices, they are great considering what you get.
