Here’s a map of the area covered by this section. It runs from the Silom Road to the North, to Soi Ngam Duhpli in the South and Rama 4 Expressway to the East. (Although there are a couple of massage places I’ve included the other side of the Rama IV). The Western Boundary is really Sathorn Soi 10, but that’s flexible too.
Here’s our Google map of the area.
