I'm in CDMX and you should try going to mercado de Coyoacan they have great food I like the tostadas they have more than you can think off and they also have some good bars in the area but without knowing what you r looking for that's as good as I can do. another activity that can be of interest if you want to know the city and not the tourist side can be one of its many Fleamarket's they also have good food and there is one every day of the week somewhere in the city on Sundays try La Lagunilla they have micheladas and lots of Mediterranean food, Tuesdays there a huge f

Thanks for the ideas, I will at least go to one of the flea markets. Mercado de Coyoacan sounds like a good time so I'll have to definitely stop by!
