If you haven’t been to Brooklyn Farmacy yet, you’re missing out on amazing egg creams and one of the most adorably quaint locations in the borough. Remedy that by dropping by the pharmacy-turned-soda-fountain this Tuesday, when they’ll be hosting their biweekly Old Time Musical Jam. On Tuesday night and every other Tuesday thereafter, drop by the Farmacy for homemade soda, gigantic sundaes, and the chance to either join in on or listen to talented musicians playing old-school instruments like the banjo, fiddle, and harmonica. They encourage jammers of all levels to get involved, so dust off your grandfather’s instruments and start working on some tunes.
