This place is pricey but it's certainly an experience, which explains why this place requires reservations months in advance. Make sure to book the bar seats because getting to watch their skilled chefs is what makes this place worth it. You get a large number of unique kinds of sushi during the omakase that most other sushi spots won't serve, such as bonito. Also, you get ootoro which is amazingly buttery tuna. Also take note that the entire dinner can last around 2 hours since the chefs are painstakingly crafting your sushi slowly and carefully.
Oh and they do use a lot of wasabi, but they do let you know at the beginning of the dinner to let the chef know if you don't want as much wasabi or more soy sauce, etc. Each chef only takes care of a couple of patrons, so this is quite doable for them.
