Definitely get the ice box and the ootoro (fatty tuna) tartare if you are here for sashimi experience. The ice box will allow you to sample a whole range of seafood, including, but not limited to, tuna, fatty tuna, salmon, mackerel, octopus, scallops, etc. The spicy tuna on crispy rice wasn't too spicy, but it definitely had that delayed heat at the end.
The amazing service and the loungey type of seats upstairs made this whole food experience even better.
