such a great place with very historical buildings! there are some nice cute restaurants, the church and tons of museums close! its great to park your car and walk around but if your going to be more than a couple of hours take a taxi because parking with cost you! also do some research before about events going on in the zocalo, theres usually something, and army expo, the ice rink, etc. i visit zocalo at least once a month, one of my favorites!
