An array of picnic tables with umbrellas are scattered on the grass, where a trailer and a food truck park. One sells clams and oysters you can get by the pound, and cook them yourself on the charcoal grills (bring your own charcoal). Some families bring elaborate picnics, with burgers grilling away, and sit down together to shuck oysters for starters. A boom box plays reggae and old '80s rock.
There's a bike and surrey rental stand next door, and the park's strange post-modern restroom complex, all of which puts the Jolly Oyster at a good location to attract passers-by. The park's liberal rules allows guests to bring their own wine and beer to picnics, making for a convivial crowd.
