"Prohibition is located in a mixed retail and restaurant development. In the back of the lower courtyard is the door to what appears to be a defunct antique shop. Beside the door is a large red phone booth. You simply enter the booth, dial the number on the old fashioned rotary dial phone, and a secret door in the back wall of the phone booth opens up."
You can read a detailed review here, and see lots of photos of the interior here. Via.
