Mexico City

From the avant-garde highs to the delicious street-level lows (and the great expanse in between those two poles), Mexico City is on fire, gastronomically. With young chefs pushing the boundaries of what Mexican cuisine can be, century-old fondas serving the classics and the vibrant taco scene, it's hard to walk a block without being captivated by something edible. Add bountifully rich markets and great public transportation to the frenetic mix, and you've got an incomparable eating experience in one of the greatest cities in the world.
