I visited freshboy last week. It was definitely quite Popular even on a weekday. They even had to turn away a few customers as there wasn't enough seats. However, my seat just beside the door, facing the stage was so warm, that my thighs were sweating in the airconditioned room. I guess it was a hotspot as it was definitely cooler on my way to the toilet on the opposite side of the side.
I am not a fan of drag, so despite the faboulous customes, I was bored. They do have some explicit acts, but i don't know if it was the warm tempreture or other factors that didn't peek my interest on the performers.
With regards to the bill, it was a more affordable 400 baht. When they came back with my change, it was in shiny new 10 baht coins.
