If you go into Peggy Kinnane's, there's a photo hanging right next to the bar of the old building that stood on that corner. A friend of mine took that photo and its companion (of the new building right after it opened).
Frankly, I always thought New Hong Kong was okay-- I've gone there a few times since 1990 in both locations. Chin's and South China were much better IMHO, at least until they both went under new ownership earlier this year.
