A pioneer in Philly’s craft coffee scene, Elixr has long been a go-to spot for businessfolk and downtown travelers shopping Walnut Street. The café is known to turn out an acidic, caffeine-potent, thoughtfully sourced cup of coffee roasted in-house. Wraparound wall sofas in the corner inside this rustic-chic, wood-heavy space make it a suitable place to meet a friend for coffee—just don’t plan to stick around too long; despite its spacious outfit, it gets quite crowded.
