Bethany and Warr Acres are in the suburban inner western part of the city and are largely surrounded by parts of Oklahoma City proper. These suburbs are home to the metro's most competitive tax rates, and have attracted numerous big box retailers. There are a large number of historic motels, restaurants, and bars along old Route 66 (now NW 39th St). Lake Overholser, the city's oldest lake, is surrounded by upscale housing and has recently seen proposals for resort development on its shores. There are growing Korean, East Indian, and Pakistani communities in this area.
