there is a bar in ipanema on rua de amoedo. it is defenitely not a hustler bar. however, many gringos bring their night catch for a drink before they leave for the day, and the boys know about the place. the tonemai serves expensive coctails. but the boys usually walk around and they look, if someone, will invite them in and buy them a drink.....
repeat, it is not a hustler bar, but you can meet a boy there. also wifi is working. don't forget about grindr. many around.
