Cooking is a major summer past time on Fire Island. The Pioneer Market in Fair Harbor is beautifully stocked with fresh produce, meats, seafood, gourmet deli, baked goods and many organic and gluten-free products. Order online, or stop by and have groceries delivered. When the going gets hot, take the kids next door to Unfriendly's and get a nice cold ice cream cone. Hangry? Grab a burger, grilled cheese or fresh quesadilla. Open May-October.
