I live in the island, so my review might be a little biased.
Bibis place offers a great location for a half a day of fun, you can only get there by boat and there's no regular tour that goes there, so you will have to contract your own ride from one of the docks on the mainland. If you don't want to rent a boat to get there you can tag along with BIBI, he leaves from the police marina at around 11AM and comes back around 7PM, he does charge you an insignificant fee.
About the restaurant, the food is excellent, but make sure you order right when you get there, as the kitchen service is very slow, also make sure the waiter is absolutely clear on what you have ordered as sometimes you ask for fish and they bring you lobster or the other way around.
