went to turtle beach in 2004 and it would have been bob marleys birthday.dont know if its the shack you mean but they were well into him,playing all his songs etc.
as for the food i dont know, though a boat full of tourists did turn up to eat.also there was a little bit of bother with some white guy and the shack boys.dont know what over,think he was abit drunk
