I've been to the morimoto in NY, and was excited to see that one opened in MGM grand. the food is pretty good.
surprisingly, the best thing i've eaten here (and in NY) are the RIBS. nope, not the fancy sashimi platter or nigiri or that yellowtail stone bowl, THE RIBS. In fact, those ribs (off the appetizer menu) was probably the best thing i ate in vegas and i'm a total sushi whore. GET IT.
