Its the southernmost end of the oceanfront that is home to Miami's gay community and tourist venues. South Beach, technically not part of Miami at all but rather of the city of Miami Beach, South Beach or SoBe is where the party's at.
Take a stroll down Ocean Drive, where you'll pass restaurants, bars and clubs on one side and the beach on the other. If you like shopping, then take a turn onto Lincoln Road, whose open-air mall is sure to make your mouth water. Once you've shopped 'til you drop, head for your hotel, dress to the nines, and hit the town!
South Beach is high-energy and high fashion. It attracts a fast-lane crowd, including a lot of New Yorkers who commute down on winter weekends, muscle boys, circuit queens, lipstick lesbians, and everyone in the fashion business. The center of all the action in South Beach is the Art Deco District. The area between 6th and 23rd streets and from Ocean Drive west to Lennox Avenue. Overall, the crowd is mixed, but gay folk are everywhere, and make no effort to hide their sexual identity.
