If you had to choose one place to symbolize Rio’s Belle Époque, it would be this sumptuous café, a must-do for every downtown visitor. Built by a Portuguese family in 1894—when Rio still evinced the splendor of a former imperial capital—its art nouveau–inspired refinements like huge mirrors, imported from Europe, wood furnishings, immense chandeliers, and stained-glass transoms welcome patrons. Colombo is all so terribly majestic you could be at one of the Continent’s grand salons or even the Tortoni in Buenos Aires
. Perfect for afternoons over a pastelzinho de Belém
, Lisbon’s traditional sweet egg tart.
