We just returned from two weeks on the Emerald and was hopeful that they would have the seafood buffet with lobster claws, shrimp & crab legs but there were only shrimp, mussels & scallops the first week & only shrimp the second week. I believe it was the first week that we had crab claws in Cafe Carib during the week but they were almost impossible to open & hardly worth the effort. My wife asked the waiters for an opener & he did get one but he didn't leave it at the table. He stood there & opened each claw as I ate it....weird. I do not like having someone stand over me & feed me morsels of food.
The main dining room did have the lobster tails & large shrimp on both formal nights.
