Puerto Madero is a great place, and if you want to go home with the feeling that you really got to see what the city has to offer, you have to come here at least once. It's called "Puerto Madero" because there used to be grand plans to build the new harbor of Buenos Aires here. The project was a complete failure. There are about 20 red, brick buildings all in a row here, which used to be old warehouses, and once the project failed, this area closed down and all of the old warehouses were abandoned and inhabited by rats. However, it's a different scene today. Almost every one of the old warehouses has been restored, and nowadays they house restaurants, apartments, offices, and one of them houses the Catholic University. You'll find the yacht harbor here, 2 museum boats, and the Hilton Hotel as well. On both sides of the water there is a lovely, clean, relaxing promenade which I highly recommend strolling, and definitely you should eat in at least one of the restaurants. Many of the city's well known restaurants are located here, like Cabana Las Lilas, La Cabelleriza, Happening, Bice, and so forth. You'll also find a TGI Fridays. Yes, alot of tourists go here, but also locals (locals with a little money) so prices are higher than some other areas of the city, but nonetheless, it's a must see.
