The building's sign had the address clearly marked along with the phone number, 397-2011, and the hours of 8 to 6. The phone number now appears to belong to a day care center - please do not call.
The entrance used on the show was actually on Mildred Avenue (Washington Boulevard is just to the left), but the whole corner has now been replaced by a small office building. The houses to the right have changed slightly, but are still recognizable. View in Google Maps
