Love the seafood here. Reminds me of when we used to go from Hackney to Leigh-on-Sea and eat fresh oysters, cockles, winkles and prawns etc by the pint and straight out of the sea. Though the water was a lot warmer in Essex than in Portugal annoyingly.
In Lisbon they don't eat many oysters and scallops so those are actually more expensive than in London - if you ask why not they tell you it's not good - but they love octopus, squid and cuttlefish (I got chatting to a taxi driver who told me about diving for them), clams and mussels and razor clams too. Also percebes and of course prawns, one time when we went to Ramiro we had small prawns, normal prawns, king size prawns, langoustines, crimson shrimp (or is it scarlet), giant tiger prawns and a lobster. There are a few gradations in-between that we didn't have i reckon but bear in mind that the crimson shrimp and tiger prawns are the size of a small lobster and the lobster was the size of a giant lobster.
Also if you travel to a different region eg Setubal which takes less than an hour to drive to then it's a different taste and they do like oysters etc which is strange. Like how you can't get lamb in Lisbon but you can in other regions.
