I’ll be arriving an 545am. Any good markets to have a Mexican chocolate drink and other bakery goods?
Mexican markets generally don't offer neither chocolate nor bakery goods. If you want an early breakfast, I would recommend Rosetta Bakery (Colima St. in Roma), but if you want something more traditional you can take a hot atole and a tamal. There are tamales stalls in many corners of the city, so it won't be difficult to find one.Edited: 05 July 2018, 17:34
I believe that Churreria El Moro -- the original location, in the Centro -- used to be open 24 hours a day, and probably still is, for churros and Mexican hot chocolate. The Rosetta bakery in Roma is wonderful, but I'm seeing that it opens around 7/7:30am.
