Really, reeaaallly small place in a small and hidden plaza... but food is great :) Make sure you call ahead to make a reservation because if you don't, you may get turned around. Yup; that happened on my first visit. The waitress said we should come back another time with a reservation because they were packed for the night. Disappointment, especially when we weren't from the area... but we made sure to reserve the next time.
There is a very limited number of seating here; but in a way it's good so there's less noise and the waitresses can actually pay attention to you. Having said, customer service was also great.
Sashimi was really fresh and presented nicely - there's not a specific one to recommend; pretty much all of them were spot on. It is a bit on the pricey side but you do get what you pay for.
Check the opening hours too as they are only opened a few hours a day, with a few breaks in between. Not exactly recommended for group visits because of the size (unless you rent out the place) but do go with your significant other or a few friends.
