Silom Traffic is always at a standstill - can't really fight it. Taxi motocy makes all the difference. Weaving in and around the parking lot of the Silom district. Used them daily - not for the faint of heart, and pay serious attention to your knees, real medical problems if they come in contact with an immobile vehicle.
Lumpini - spend many, many, many hours in there. Excellent hideaway. You don't realize you are in a city.
