Blanchards Beach Shack opened in December 2011 next door to Blanchards Restaurant, which has spent years on best-of-the-Caribbean lists under chef Melinda Blanchard. The Shack is the deliberate opposite: picnic tables in the sand, biodegradable cups, and a buzzer that goes off when your lobster roll is ready. On an island where dinner can run three figures a head, that counts for something. Happy hour Monday to Friday, four to six. Closed Sundays, and the lunch crowd lands around half twelve in high season.
