Boteco Belmonte is a popular bar chain in Rio. You will see them everywhere, but this is one of my favorite locations. Tucked away in the small streets of Leblon, this place tends to get very busy on the weekends or whenever there is a soccer game happening.
Belmonte is known for serving incredible local food. I highly recommend trying their classic "Filé Oswaldo Aranha" and some of their snacks options.
