Eating street food in Mexico City will get you in trouble----unless you know where to go. My neighbors took me to a new hamburger stand in the Palo Solo district, the neighborhood just west of where I live for what could very well be the greatest street hamburger in Mexico City.
For 3 bucks you'll have a burger piled with bacon and cheese. Nothing is wasted. Even the bacon grease is soaked into the bun on the grill.
