Informal commercial districts begin at the Lake Calhoun area which marks the end of West Lake Street, followed by Uptown, and then by Lyn-Lake. These areas generally have high property values and fairly high density. In the early 20th century this was one of the busiest areas outside of downtown as the streetcars headed west to Lake Minnetonka. Today they are among the most popular entertainment and nightlife areas in South Minneapolis, and the site of rapid condominium development in recent years.
