Don't know about the seafood here but I always get the duck. Yummy! If your DH ia a big seafood lover you should try the Flying Fish at the Boardwalk. It one of my Disney favorites and it a quick boat ride from the International Gateway. Also Narcooeess at the Grand Floridian is another great seafood restaurant.
Sometimes Chefs has a yummy mushroom tart for an appetizer.
I've had scallops and shrimp, very good. I think they also have a salmon entree, but I have not had it there. I have enjoyed chicken there (usually avoid chicken when I am out because I eat a lot of it at home, but it was quite good).
DH loves their flatbread apps, I like kir royale and we both enjoy the creme brulee. Have a great meal!
