I am puzzled, as some others are, if you wouldn't be happy with the food from Dreams, where do you normally dine on island? A private chef might be a good idea, but I have no idea where you would be able to do that, that it would be on the beach, unless you rent a villa that's on the beach. True villas on the beach in SXM are fairly expensive, although I'm guessing your budget for this event must be fairly substantial..
