Café Equis
Open since 1930, this coffee spot on one of Centro's most hectic streets is one of liveliest places in town to sip a cortado (espresso mixed with warm milk). Café Equis is by no means a third-wave coffee joint—the beans here, entirely from Mexico, are a touch over-roasted and you won't find any plant milks on offer—but with its painted walls and lively air, it's a bona fide institution.
