Can someone explain the process, what it is? A place called Foxgy just came across my timeline. I think it used to be called sit2sis? Is it for entertainment, do you take the guy home? Is it a place where you just hang out with a guy and you basically spend all your money?  What are the processes, is it worth going?

This thread has plenty of information on Boy Karaoke aka host bars:

Note that Sis2Sis always had a reputation of being one of the most expensive host bars in BKK, I have seen clips on TT of a boy being gifted an iPhone by his female admirer! I have also seen bids of 16+ drinks being made for a single hour of host drinking company (16x250b = 4000b an hour!)
