RSVP is a must. The staffs are very nice, and the chef also speaks some english. Although it is pricy, i think it's very worth it (this is my personal opinion, since i am comparing to pricy sushi restaurants in tokyo). The chef presents some sushis from the japanese comic book and actually said "shota-no sushi" lol Since this place is in hokkaido, try the uni and ikura sushi.
