Paris Bath Houses

This bath house looked clinical. Was it a jewish sauna?
I remember one called L'Opera (I think) in the corner of a flatiron building. It had a raised pool in that triangle with a restaurant around it, and a movie screen at the angle. I remember having an avocado there with an "Israel" sticker on it! I ate well at that bath house, and served as an entree for some lucky Frenchie.

Aime-moi moins, mais aime-moi longtemps
