In celebration of its two years of pouring its boozey knowledge all over the web, Drink Philly is stepping up its monthly First Friday fests tonight. There will be live jazz, art and Moonshine Margaritas from Philadelphia Distilling. But surely the highlight will be a whole roasted pig, served up by McCrossen’s Tavern chef-owner Townsend Wentz. The evening also serves as a benefit for Alex’s Lemonade Stand. Things get underway at 5 p.m. Check the website to RSVP.
