Plaza Cortázar (ex Plaza Serrano) is a popular meeting point at sundown. The surrounding streets are full of design shops, good restaurants, fashionable bars and terrace cafes. Plaza Costa Rica with bars restaurants, and a merry-go-round for kids is another option.
Tip:
At the corner of Dorrego and Niceto Vega, you'll find the Colegiales flea market, an antiques fair where you can find everything from restored furniture to old records.
