I took some visitors from abroad (including my gf at the time) to cafe con piernas and they all thought it was quite interesting. Indeed you went to the tamest of them all (and the one that started it -- it was cafe caribe who changed the concept of a coffeeshop to the legs version).

The happy minute was popular at a placed called "Baron Rojo" (Red Baron), where the girls definitely wear way less clothing and at random times during the day they would loosen up their tops for a minute. (I think this place went out of business, but I'm not sure...haven't been back to Chile for a couple of years now).

Some of the tainted-window places do serve alcohol, the music is really loud, and every time they open the door, there's so much smoke inside that you could probably make bacon.

For me one of the most amusing parts was always the people who would hang out outside the Red Baron waiting for the doors to open so they could catch a glimpse without buying the coffee.
