Wow, no bars at all?!
I think the first time I went to Soi 33 was in 1992, when I started living in LOS, and I became quite a regular. I think there were 5 or 6 bars back then (Renoir, Vincent Van Gogh, Degas, Monet and a couple of others) although we mainly frequented Renoir. Over the years a few more opened on the main soi and sub sois and then it sort of took off and a map of the soi dated March 2010 shows about 40 bars, including many Japanese ones, and about 15 massage joints. So to go from 40 to 0 in 10 years would be a massive collapse!
