A black market
bar where shots of liquor can be bought at low prices straight from the bottle. Many shot houses also sell beer after hours. They are usually run out of someone's apartment or house and known only by neighbors.
Shot houses are also a common place for people without official identification (whether underage or illegal immigrants) to buy alcohol.
