Omakase and fresh wasabi. That's all you need. The omakase (chef's choice) is probably thee best one I've had and I'm comparing it to some great places in LA. A bit different in that it all comes at one time instead of one at a time but I had no problem with that. And the price?! OMG!! ONLY $35!!!!! What a deal. What a steal. And you will leave pretty full.
And fresh wasabi. You should definitely try it if you haven't yet. I can't stand the paste but eating it fresh is a whole different experience. It's worth the drive to downtown.
