So take the opportunity to try a little bit of everything, such as tamales, moles, enchiladas. The authentic Mexican cuisine is one of the best in the world.
The Zócalo, an immense plaza in the center of the city, is the heart of the city and the country. Both the cathedral and the remains of the ancient Mayan capital are well worth a walk. Very close to the city is Queretaro, a beautiful and colorful colonial city, with its alleys and squares.
