Reddit reviews Eat Mexico: Recipes from Mexico City’s Streets, Markets & Fondas

My favorite tacos are carne asada and carnitas. Here are some very detailed articles on them:

I'd also highly recommend this book: https://www.amazon.com/Eat-Mexico-Recipes-Streets-Markets/dp/1909487279

It's not tacos, but one of my favorite recipes from there that I've tried so far can be found here: http://www.epicurious.com/recipes/food/views/enchiladas-verdes-green-chicken-enchiladas-56389864
