Go onto the web and search for the area you want to see a girl in.
I think brothels as we have here are illegal but you can find lots of girls working out of single units or townhouses all the ones I visited were or appeared to be on their own so you need to book and then its a bit of pot luck.
I went for Asians but there are a lot of other nationalities and the price range is from reasonable to over the top so check the price and what you get when you book.
