As far Hama and Izumi's go, I'd have to vote Izumi's the better place purely for sushi, but Hama definately has some interesting fusion-y stuff going on. Another couple of places to look at if you're considering something higher end is Dream Dance, located in Potowatomi Casino. Emphasis on game, steak, etc. Or there's the fairly new Bionda (sp?) in the village of 'Tosa...I believe it's where Jolly's on Harwood used to be. If you're looking for foie, caviar, and truffles, it's probably the place to go.
