No 7 and No 13 seem to be Models who go around handsome man competitions collecting prizes and money. I am pretty sure that they don't work in bars. I did **** into No 13 on the pedestrian footbridge across Rama IV near Soi Ngam Duphli.
No 12 Mr Chang works at Crystal Boys Pattayaland Soi 2 but is often booked before the bar opens.
They do have some handsome muscular guys there and athletic types also. The show is a yawn unless you are into snake dancing or unless Mr Chang is there - he is pure magic in movement and the sadist number is great fun.
