If the Frommers review of the latter’s Tokyo location is any indicator, this is going to be the best thing since Benihana:
Customers sit at a long, U-shaped counter, on the other side of which are mountains of fresh vegetables, beef, and seafood. And in the middle of all that food, seated in front of a grill, are male chefs ready to cook whatever you point to in the style of robatayaki. Orders are yelled out by your waiter and are repeated in unison by all the other waiters, resulting in ongoing, excited yelling. Sounds strange, I know, but actually it's a lot of fun.
And Bruni can practically review it from his desk!
