Seafood Restaurants In Ny Will Seafood Restaurants And Sushi Bars Accommodate My Shellfish Allergy?

Will seafood restaurants and sushi bars accommodate my shellfish allergy? - seafood restaurants in ny

I like going to a restaurant for seafood and / or many sushi bars, but I am a little worried about cross contamination. I eat all the fish, but I'm allergic to (lobsters, crabs, shrimp, etc.), shellfish can be useful for me (especially in a sushi bar), and my specific allergies, or do I avoid the seafood?
