Fonda Margarita
Everyone from postclubbing revelers to early morning workers to ardent foodies (the late Anthony Bourdain was a big fan) wait in line for a chance to feast on the hearty guisados served in this legendary breakfast joint. Come with a big appetite, and try a few specialties, such as refritos huevos (eggs whipped with refried beans), chilaquiles with salsa verde, and eggs stewed with longaniza sausage. Many of the best dishes sell out well before Fonda Margarita closes at 11:30 am, and there's usually a line by 8, so try to get here early.
