We prefer K or Mary's Boon because of the location in the center of Simpson Bay tends to have no or less Seaweed and a better breeze than the corner of the Bay. Service at Mary Boon after Covid was slow but that had a management and staff change a couple of years ago and its as good as any of them now. Food is good at K and Mary Boon with Mary Boon being less expensive with nice menu and portions. If you are going to Mary's Boon on the weekend go early because it is always packed full by Noon. I see there is another beach bar next to Mary's Boon and K but I heard its might never open because of illegal permit issues.
