Try Babalu Resteraunt in Mpls: http://www.babalu.us/
It's carribbean cuisine and it's really yummy. They are the only resteraunt that I know of that makes Paella which is a spanish/carribbean dish of rice, mixed with lots of seafoods like squid or calamari and includs clams and muscles in the shells. (You have to dig the clam or muscle out of the shells with your teeth...very yummy and my husband and I have only ever gotten it in Spain, until now. It is a little expensive, but worth the money.
You could try sushi, but find a good one...not just any sushi resteraunt will do...sushi has to be good fish for it to be good. Try Kikigawa in Mpls or Saji Ya in St. Paul. Even Beni Hana makes good sushi.
