Opened in 1928, this cantina lies in Coyoacán. From the entrance -- off a narrow cobblestone street -- to the antiquated bar, a sense of nostalgia permeates the comfortable, jovial cantina. The operation is as traditional as the menu. For those who are only drinking, waiters bring the customary small plates of complimentary snacks (called botanas) that range from crisp jicama slices with lime and chile to pigs' feet in a red sauce. It's easy to imagine the communist conversations that must have bounced off the walls here in Frida and Diego's day.
