The rooftop patio at Maison Mercer in the Club District played host to a swanky soiree last Thursday night. The occasion? Italian liqueur brand Disaronno was serving up complimentary cocktails and finger food to an appreciative gathering of media, booze-seekers and fans of the band The Reposadists (Reposado's house-band) who happened to be providing the entertainment for the evening.
