If you’re staying in Mexico City on a Sunday, you’ll realize one thing pretty quickly - almost all the restaurants and bars are closed. But don’t get too discouraged - just go to La Docena. This loud, informal seafood/oyster bar in Roma is open all day on Sunday (and the rest of the week), making it a great option if you’re looking for a late dinner with friends that doesn’t involve raiding the chip section at the nearest grocery store. All the seafood and cocktails are excellent, but definitely get involved with some cured meats too (they’re cut fresh by a guy standing in the corner). Bonus: Across the street is Churreria El Moro, where you’ll definitely be heading for some post-dinner churros.
