We loved the first run of the Feirinha Gastronômica – a series of Sunday food fairs with chefs and amateur enthusiasts alike serving up dishes. The only downside was the tight squeeze in a charmless car park in Vila Madalena. The food fairs are coming back, only this time bigger (with 30 stalls on rotation each Sunday) and better located – in a space with a retractable cover in the leafy Praça Benedito Calixto, best known for its Saturday afternoon flea market.
