This is an expression of what Rio is, ppl gathering around a square, playing music and having a beer. If you like this kind of atmosphere, this place is awesome. There are many bars and restaurants around the square, so you can grab something or even sit a while and do my favorite thing, people watch.
Popular square surrounded by bars and restaurants. People go there for drinks at night every day and it is specially crowded Thurdays to Saturday. Really nice to get to know people. On Sundays there is a street market and a Chorinho band that starts playing at 11AM.
