Classic. Near the Vanderbilt Museum on the far North Shore, this tiny roadside clam and burger stand is a quick turn off from the hairpin curve close to where Northport and Centerport meet. For generations (since 1926) this has been a local haunt of Long Islanders and visitors alike. The food here is self-serve and the menu is compact, while the mood is less about being sophisticated and more one of enjoying life at its most simple. The Shack is open only in summer.
