Turkish/Greek Cafes (NY, NY and unknown, unknown dates)

I have always treasured this picture of my grandparents, which I was told was taken in a Manhattan Turkish/Greek nightclub. I would guess it was in the 1940s, but I'm not sure. There is something really evocative about it.

Today I happened to find myself listening to Maria Callas singing an aria from La Traviata. When I looked at her bio in the Wikipedia, I found this picture, which to me really resembles the picture above. Turks & Greeks, again, an ongoing theme here.
