Visitors from overseas should remember that Qatar is an Islamic country and, in line with local custom, Banana Island is a dry resort. Guests can’t bring their own alcohol to enjoy in private. But they can sip mocktails by the lagoon pool, play beach sports and hit the golf course or simply fuel up in one of the island’s numerous restaurants serving anything from traditional Middle Eastern and Asian delicacies to American diner classics and Italian fine dining. A fleet of electric golf carts is always at hand to ferry you around.
