Photo by John Wambolt, posted in the Wormwood's Dog and Monkey Cinema facebook group. "It was my privilege to help a bit in the renovation of the former Vogue Theatre when it became Wormwoods. We used to drop in to Chris' Cuisine, two doors away, when we got hungry.  
The Rainbow Room was indeed upstairs. This may have been very early February 1998 - I did a lot of street pictures at that time -- loved Gottingen Street in the rain!"
