Silom is one of the busiest roads in Bangkok together with Sathorn, Asoke, Ploenchit, Ratchada etc. The Soi 4 of Silom is an interesting street full of restaurants
Your photos are amazing. I always thought of Silom 4 as ground-zero for the gay bar scene. I used to know 2 guys who worked there. Interestingly they are straight (both have since married and retired)
