Beer is beloved for many reasons, from its flare for temporary problem solving to its miraculous ability to make pretzels even better. Celebrate beer's strengths at Park Slope's Die Koelner Bierhalle. Expect pretzels, sausages, beer, oom-pah bands and communal wood tables aplenty. If you're enjoying yourself a little too much, you might also expect slight memory loss and a hangover. Pro tip: Weekends can get busy so upgrade your pint to a liter or better yet, a boot.
