I'm hoping for recomedations for wonderfully good Japanese Restaurants in LA. I'm taking my husband for a surprize trip and don't want to disapoint him. I'm interested in taking him to someplace refined and traditional. He's a traditional sushi chef, so I need to pick well. I need something beyond hamachi, tuna and rolls. I read interesting things about Ginza, but saw mixed reviews on citysearch (which I don't trust to guide me). PLEASE HELP! He's never been to LA & I don't want to look stupid.
