My son is turning 18 and LOVES sushi. I would love to gather a group of his friends and family for a sit down sushi experience, possibly in a tatami room. Ideally, the meal would also include some cooked Japanese specialties as well, but we all really love excellent sushi. Some of our other favorites include Sushi Gen and Nishi-ya in Glendale but I don't think either of these has places for a group to sit in a private room.
Any suggestions are really welcome!
