Well, you could sit on a bar stool and drink beer until you fell off the stool ... saw it with my own bloodshot eyes. Sukhumvit Road/ Soi 4 has lots of bars where you can nurse a cool one and watch the show. Crusty old men, with weathered faces, walk hand- in- hand with Thai girls half their age...their outfits so tight that they must have been poured into them.
Try walking into "Pharaohs" or "Spankys" without getting hit on - not gonna happen. But there are other serious pursuits....such as the full Thai body massage. More about that later.
