Californians... No concept of money.
Joking aside, that'd be a good price over here in the farmlands if the sushi is even just average. There is an all-you-can-eat buffet here that keeps a small-ish amount of decent sushi out. I've found that if I go at 2pm I can load up and get a ginger high for $10.
>100+ pieces here in Copenhagen
Damn, that was great. Wasn't *wildly* expensive, as I recall.
