We have ordered their GF sushi options and really like them! They are more plain but thought the salmon in the salmon roll seemed like great quality. Their GF rolls are much smaller than their other rolls. My husband eats 3-4 rolls and I eat 2-3. Wednesday's they have half priced sushi and wine so it's affordable!
HyVee is a regional supermarket with a great attached restaurant and bar. GF menu items are clearly marked however, many items are listed as GF but fried in contaminated oil (such as the "GF" fries) so be sure to ask specific questions of the server to avoid ordering misleading items marked GF that will make you sick. The GF sushi was great and they offer several options (tartare, nigiri, rolls). They have GF soy sauce available upon request. Double check with the server as it comes in the same unmarked little cups as the regular soy sauce.
Friendly & knowledgable
