Generally, taprooms serve beer straight up in a pint glass. This Friday, Sisyphus is mixing things up—literally. As usual, they’ll have a wide variety of beers on tap, but the comedy club, housed in a room separate from the main pub, will become a speakeasy. Here they’ll serve five custom, one-night-only beertails (aka cocktails made with beer). Sisyphus threw a similar party a year ago. Now it returns with “beertender” Andy Robertson and his secret concoctions. Word on the street is that the ingredients will include botanicals, fruit, tonics, and a special barrel-aged stout. Once inside, be sure to whisper the secret password: New England clam chowder.
