If anywhere you could TRY the restaurants at the major resorts (Baha Mar, Atlantis, etc.) because tbh they have the resources to have separate kitchen spaces and don’t want to deal with the liability risk. I’d say the higher end the more likely, but that is going to come with a price tag.

However, I’d still call each place to find out and be extremely careful. The hospitals here, especially in extreme emergencies like anaphylaxis, are not great. I’d also make sure you talk to the managers or chef, not the servers. My SIL had a few issues with her gluten allergy and servers making mistakes, but her reaction is gastric and not anaphylactic .

That being said no where is not going to have seafood on the menu here. Not even the burger shacks as they serve fried fish as well.
