El Beneficio de la Duda
This dapper all-day café with white-brick walls, colorful peltre dishware, and fresh flowers on every table is in a semi-residential section of Coyoacán, well-removed from the crowds and an easy stroll from Museo Frida Kahlo. The owner uses organic coffees and, as much as possible, locally sourced ingredients in the European-influenced Mexican fare, which includes superb chilaquiles (order them with both the green and red sauces), panfried potatoes with paprika and chipotle aioli, and ham-gruyere croissant sandwiches. If you're having trouble finding a seat, there's a smaller location (it's actually the original) around the corner.
