Patts is short for "Pattaya" which is nowhere near Patong.
There are a couple ladyboy shows in Bangla. You can't miss them if you do a walk along Bangla Road and ask a ladyboy where to go for a show. They will charge huge for drinks and try to get tips for pictures after the show.
My girlfriend and I go to Patong every couple weeks and always go to watch the ladyboys...I don't know why, we just always seem to end up there.
