The Harrison in Floral Park and more Long Island restaurants to try this weekend

Squeezing every last drop out of summer is the guiding maxim these days, and dining al fresco is a swell way to do that. While many flock to waterside tables, out-of-view patios and courtyards hold a special, sometimes enchanting charm. Here are three places that aren't exactly visible from the street, but have outdoor tables and those secret-garden vibes (plus, great food to boot).
