A small, neighborly store, Q.C. Liquors is wedged between a Radio Shack and a nail salon in the Shops at Queens Chillum. Inside, elderly men sit at a small table and talk, a woman buys lottery tickets and the shelves are stocked with liquor. A visitor might well be welcomed to join the discussion at the back of the store, which carries a selection of beer that ranges from Bud Lite and Corona to Dos Equis and Heineken.
