Spanish isn't my thing, though I now have the excellent spreadsheet...
However, I need some help with getting a concept across. Mrs_G doesn't eat shellfish (prawns, lobster, crab, oysters etc) but is fine with fish.
Could anyone help with how I explain this to the restaurant? I should add it's a dislike kind of thing rather than dying, so not an allergy. I'd hate to be sitting at El Celler de Can Roca and them do three seafood dishes for her, the odd tapas I can scoff on my own.
Help appreciated (I'll probably write it on a card....)
