1. DON’T…eat the bologna sandwich at Mercadão.
It’s easy to understand why people enjoy it so much: It’s cheap and big enough to share. But it’s also difficult to bite into, and to get one you have to wait in an enormous line at the popular Mercado da Cantareira, the central market that paulistanos call Mercadão.
DO…eat oysters instead.
In São Paulo, as in most cities, a visit to the central market is mandatory. Try Mercadão on a weekday and look for fresh oysters at Casa das Ostras in the seafood area (closed on weekends). They’re super fresh and you can buy them for R$3,50 each, or a dozen for R$20. Eat while enjoying a cold beer and taking a break from the lunchtime heat.
