If you enjoy sushi, and want to try EVERYTHING on the menu but are afraid to, this is definitely a great option for you.
You can eat as much as you want, and there is so much to choose from. I've only been to Todai for Dinner, which I found to be somewhat expensive (20ish a person), but I do intend to go back for lunch. I don't think it's really worth the price for dinner.
The sushi was good, considering it is buffet style and thus has to be pre-made in somewhat large quantities. It certianly is nowhere near as good as fresh sushi made in specialty restaurants, but like I said , the variety is a lot of fun to sample.
The hot dishes and desserts were also very tasty.
