On the eastern edge of downtown is Greektown. What was once just a block of Greek restaurants has now become the center for Detroit nightlife, with its many eateries, bistros and clubs. One of Detroit's three temporary casinos is drawing additional people to the area. Adjacent is the restaurant-and bar area known as Bricktown, and near that is the towering Renaissance Center. East of the Renaissance Center, along Jefferson Avenue, new housing and retail developments are taking shape beyond the restaurants and clubs of the warehouse district known as Rivertown. Other pockets of activity include the Cobo Convention Center and the Joe Louis Arena, home to the National Hockey League's Detroit Red Wings, and the western outskirts, where two more temporary casinos have opened. Most of downtown's sites are linked by the People Mover elevated train system.
