Maybe I am a traditionalist but I like either simple nigiri or temaki not into the fancy smancy rolls. Unfortunately, one of my groups entrees came with undercooked mash potatoes (you know when you don't cook that one potato long enough and it can't get pureed enough so you end up with gritty sandy bits in your smooth mash.) we were offered a substitution but I think basic food prep should be on point for a place like this.
