Long Island Summer Lounge isn't your typical German beer garden. Located in downtown Frankfurt, this hip rooftop watering hole may be a ways from the actual Long Island, but it does an impressive job recreating an upscale nautical vibe. From the two pools to the white cabanas and tangerine lounge chairs, you might forget you're in the central city district for a minute. The drinks list features classic cocktails, champagne, and, of course, German beers like Schöfferhofer. After soaking up some sun poolside, refuel with such quintessential barbecue fare as hot dogs, burgers, or steak. The lounge is open every day during the summer, but in case of questionable weather, check the open/closed status on the website before heading over.
