Howl at the Moon Boston, Boston

Howl at the Moon’s trademark dueling pianos serve as the epicenter of nightly celebrations, as patrons submit their favorite songs on slips of paper for the pianists and backing musicians to recreate. If the website’s playlist is any indication, the bands can handle popular songs from all genres and eras, from Bon Jovi’s “Livin’ on a Prayer” to Kanye West’s “All of the Lights.” The performances are spirited: colorful lights splash upon a stage where servers, guests, and chairs that have somehow developed mobility all dance along to the music.

Fueling the celebration is the bar’s indulgent selection of drinks. Servers stand over patrons to plunge jello injectors into their mouths, and revelers grab colorful straws to help drain 86-ounce booze buckets filled with sangria or other fruity libations. Pomegranate liqueur and honey-infused whiskey sweeten specialty cocktails, and local beers add depth to coolers stocked with Sam Adams and Harpoon IPA.
