oh! I remember walking past that one (near a temple) and I always use White Orchid Hotel as a basis for where I am. Should ne easier next time. I guess that there are salivating developers looking at the old cinemas with proposals for condos , hotels or offices. No doubt the numbers of cinemas will keep declining as Bangkok changes. That website
The Southeast Asia Movie Theater Project
is quite interesting if you are at all interested in cinema history. There were certainly some enormous and grand cinemas around before multiplexes.
