What was the address of Rush Up Club in Chicago and what is now its place?

Address: Rush Up Club used to be located at 30 South Dearborn Street near Monroe Street, in the heart of Chicago's Loop.

Current place:

The building that housed the Rush Up Club at 30 South Dearborn Street no longer exists. It was demolished sometime before mid-1929 to make way for construction of new skyscrapers. There’s now what appears to be an empty and fenced lot with some trees on-site at that address which is part of Grant Park.
