Polanco has grown by leaps and bounds. Once but a neighborhood of some five modest sections, today it also includes good parts of Grenada and the none-too thoughtfully named "Ampliacion Grenada," too. Add to that a few neighborhoods of historical significance like Anzures, Veronica Anzures, and the whole collection of interesting little neighborhoods to the north of Av. Río San Joaquín, and you get something very dynamic, even a city within the city.
Polanco seems to be enjoying the slight eclipse it's received at the hands of La Condesa which snatched away the crown of "most affluent" neighborhood in the city. Polanco has always been more modest, even granted its considerable affluence.
For international visitors, even those staying in La Condesa, Polanco is attractive for a few of its really good museums, and for the formidable shopping district along Avenida Presidente Masaryk.
Further north still, ancient Tacuba marks the end of the famous México-Tacuba Causeway. It's surrounded by important landmarks and sites in every direction.
