Windsor has often been the place where many metro Detroiters find what is forbidden in the United States. With a minimum legal drinking age of 21 in Michigan and 19 in Ontario, a number of 19 and 20-year-old Americans frequent Windsor's bars. The city also became a gambling attraction with Caesars Windsor's opening in 1994, five years before casinos opened in Detroit. One can also purchase Cuban cigars, Cuban rum, less-costly prescription drugs, absinthe, certain imported foods, and other items not available in the United States. In addition, some same-sex couples from the United States chose to marry in Windsor prior to 2015, when same-sex marriage was legalized in all 50 U.S. states.
