Rio Minho
The elaborate Portuguese tilework, bow-tied waiters, and first-class seafood dishes make this lunchtime, weekday-only spot one of the top picks for an atmospheric lunch in Rio's downtown. Perch at one of the alfresco bar-stools for a more informal snack, or head inside to dine in the colonial vestiges of one of the city's oldest restaurants, serving the city's well-to-do since 1884; if you're on a budget, opt for a snack at the restaurant's more affordable back annex.
