The business district and riverfront feature land-based casino gambling, restaurants, bars, and shops that attract tens of thousands of visitors each year. Although much of the outer city's architecture is typical suburban design, the city's downtown district retains early twentieth-century architecture. A few blocks east of the main business district is the Riverside district, featuring tree-lined brick streets full of turn of the twentieth-century homes. The Reitz Home Museum is one of the finest examples of French Second Empire architecture in the United States. Other homes nearby feature similar character and design and include Italianate, Colonial Revival, and Renaissance Revival styles.
