Behind a massive bougainvillea vine that covers a century-old mansion on the corner of a quiet, cobbled street, San Telmo’s Café Rivas evinces an elegant, 1920s vibe—but the food is decidedly contemporary. The menu is short and to the point. Three prix-fixe options are posted for lunch and change daily to delight a claque of assiduous regulars. Standout items at dinner include a nightly ceviche special and the dry-aged beef. There’s also a Sunday brunch with traditional favorites like eggs Benedict. In the evening, a bartender arrives to serve up cocktails, and there’s live piano on weekends.
