Regardless of whether you stay in Puerto Madero or not, try to visit the newish contemporary art museum there that's private (an innovation for Argentina, I've been told). There are some good but relatively expensive restaurants, plus places with outdoor seating for ice cream or a drink.
There are about a half dozen other museums around the city focusing on local/contemporary art, plus of course the Evita museum.
