All You Can Eat Sushi places are great but this place doesn't live up to the expectations of a vegetarian, your options will be very limited, I think I only had 5 things that I could actually eat from the menu.
My friends who eat fish / meat said everything that they ordered tasted great and was good quality. For how much you pay here it isn't worth it for a vegetarian to go All you can eat, so I would suggest ordering from the menu instead if you are vegetarian.
It has a nice an cozy atmosphere, and service can be rather slow, but I do not mind waiting as I know good food made from scratch and with love takes time.
