Recommendation from the B4D Forum: 

A great, relaxed bar on Avenida do Sol. Owned by two brothers who are huge music fans, as reflected in the decor, and the fact that there is always great music playing, especially classic rock (though not too loud - very family friendly). All contributes to a very enjoyable atmosphere. 

During normal times, they also regularly have live music at night, especially rock and blues. Food is excellent, especially their chilli, and they serve what is a good contender for the best burger in DF. 

It´s near the end of Avenida do Sol (shortly before Ouro Vermelho), but well worth the trip.
