Paseo Independencia - The city's commercial backbone is also a nice pedestrian avenue to eat, shop, and stroll. Beware however during the Christmas holidays, when the atmosphere gets dense and pickpockets become ambitious.
Plaza de los Heroés - Located at the east terminus of the Paseo Independencia, this central plaza renovated in 2003 is a nice place to relax anytime. Avoid gypsies who will literally tease the cash out of your pockets.
