Quark's was the multi-level, vibrant and popular central attraction of Deep Space 9's Promenade, drawing crowds of travelers and station inhabitants with its offerings of drink, food, gossip, gaming and fantasy fulfillment. The proprietor of the establishment was Quark, a Ferengi entrepreneur and sometimes petty criminal who was the eternal thorn in the side of the station's Chief of Security, Odo. Despite his alliances on the wrong side of the law Quark was a capable and amiable host, and the bar was usually one of the most popular places for recreation on the station.
