We were staying in the Marriott. This "beach bar" is adjacent to the swimming pool and there are good views across to the ocean and beach depending on where you sit. The tables have umbrellas and there is also a large bar area where you can sit and enjoy the view in the atmosphere.
We had lunch there once and the food was fine but nothing exceptional. After all, it is what it is namely a beach bar on top of a hotel. We had drinks there on a number of occasions (everyone staying at the hotel receives free drinks vouchers) and as with our lunch, the service is very variable. The servers are pleasant although some of them are a little "quirky" and as other reviewers have commented the level of service can be a little erratic. In the evening there is live Hawaiian music which seems very popular with guests staying at the hotel. All in all, it is worth a visit if you are staying at the Marriott Hotel, otherwise there is nothing special about it and you can receive the same sort of offer at other hotels.
