I have read great reviews on Sushi Shibucho and am thinking about going there for the first time on Sat. I'd like some suggestions to make this as nice of an experience as we can since my husband and I rarely have the chance to dine out sans kids. How do we get a seat with Shibutani vs. the son? Do you recommend omakase or order a la carte? What are some things we must try there? Are reservations required? Any other suggestions you have would be greatly appreciated. Thank you!
