This evergreen rooftop has a new Hamptons’ beach chic look thanks to a May 2016 renovation. Get a table on the East Terrace, where you can overlook the shops of Fifth Avenue from 23 stories up. Tables are first-come, first-serve with one exception: the best spot in the house, the “Corner Couch,” which can be reserved in advance. Settle in and order a “Ning Sling,” a gin-based passion fruit mojito topped with lychees.
