There used to be a very nice one in New Orleans...big balcony section, nice concessions, sexy cajun in the ticket office. I was there once when Georgina Spelvin came a did a live show...not sex, but nude dancing with another hot porn actress. I got their autographs...
There was one popular place here that boasted "20 screens" which was basically 20 small rooms where you could go in, put quarters in the slot, and see like 2 minutes of porn. It became quite a popular place for gay prostitutes, and eventually got shut down.
Most have closed up where I live. I can't see going now anyhow...watching porn in a public theater has no appeal to me at all, but there was a time when these theaters were quite popular. Just wondering if they are still around.
