Even if you’re definition of Bavarian charm isn’t sausage-eating men in lederhosen or yodeling blondes in dirndl, you’re still going to have to check your coat at the door and head downstairs. Mario’s Keller Bar, in the basement of Gasthof zur Gemütlichkeit, serves up an array of southern German beer staples by the half liter, liter, or two-liter “boot.” This is the only place in town where you can pop a snuff board, drink from a boot, and swig apple schnapps while dancing to polka in the early evening and hard, sometimes very alternative rock after midnight. Mario’s is the kind of place where even teetotalers find themselves having one or two too many, which is why cab service to and from Mario’s is so great.
