Folks looking to start Labor Day weekend a little early may want to check in with Grumpy's Firkin Fridays. Each week, the bar sets up snack food and a cask-conditioned beer to be enjoyed by all until it's gone. What kind of beer? That varies, as the brew is usually announced the day of the event via the Grumpy's Twitter account. Past pours have included Epic Brewing Company's Spiral Jetty, Summer Summit Ale, Left Hand Smoke Jumper, Surly Bender, and other fine beers. Depending on the cask, food has included sausage, guacamole, and other tasty treats. The downtown Grumpy's also gets in on the action often, and recently offered the Flying Dog Raging Bitch Belgian IPA. The beer and food are free, so drink up until the cask is tapped. Be sure to watch the @grumpysne and www.facebook.com/grumpysdt to find out what's happening each Friday at the downtown and Northeast locations. 21+.
