Is what goes on behind the dark glass of cafe con piernas in Santiago Chile illegal?

Question

I am so confused about these places and I just started living in Santiago. I see ones we might say are clean, short skirts, and others, with women in less clothing behind black windows who walk into the street and offer me more than coffee. I just don't understand, are cafes con piernas legal or how is what is offered to me offered to me so, shall we say, daringly?

Answer 1

No, it is so you don´t see the girls from the street. Some ilegal things do happen, sure , but are not the usual.

Answer 2

also, the dark mirrors protect the customer's privacy.

Answer 3

they are just girls selling coffee, but there are many girls  want s*x with money, but prostitution is illegal that in the cafeterias..
