hmm what are caribean food specialties,
A lot of chicken and fish. Rice & beans feature highly too.
Tends to be spicy and sweet (coconut, chilli, brown sugar/honey, thyme, ginger etc etc) It's really nice - if done properly, like anything else.
have never seen a caribiean restaurant anywhere in the world
You musn't have travelled very far then ; )
They are not common, but not rare either - there are at least two that I know of in Dublin for a start and Dublin is a very minor city in European terms.
