Supersized steins of beer ain’t a bad way to say goodbye to summer. From Saturday, September 19th to Sunday, October 4th, Oak Long Bar at the Fairmont Copley Plaza will celebrate Oktoberfest with special German fare like traditional pinklewurst and hearth-baked pretzels with beer cheese and mustard sauces. Wash it all down with 20 ounces of Harpoon (for just $8!) and say willkommen to fall.  The specials are available at both lunch and dinner, so there’s no excuse to miss this autumnal offering.
