Feira do Guará, is a located in QE 23, Guará I.
This is a great place to find spices, fruits and vegetables, cheeses from all over Brazil, imported foods, salamis, different olives, chilies and much more. It is also said that here you can buy the freshest seafood and fishes from all over Brazil, including piranhas and other types from the Amazon. If you are a food lover you have to go there and check it out. Casa de Dolce e Queijos has also a shop here and they are always worth a visit.
And yeah, they sell cloths too, but that is catering more to the Brazilian style.
