If you mixed "old world charm" and "new world swagger," it would probably taste a little like dulce de leche... a beloved treat that Argentina is famous for inventing! Delicious as it is, food is just one of Argentina's claims to fame, and the local attractions and architecture keep up with the flavors just fine. Tango is another top export best enjoyed direct from the source, and the energetic Palermo Viejo nightlife is practically palpable during the day. This world city has been compared to Paris, and the history, old-fashioned confitería cafés and colonial architecture certainly all play their role, and despite all the modernity, plenty of green spaces remain. But if you're looking for the rest of the colors of the rainbow, the buildings of the riverside La Boca neighborhood show them off to visitors in all their vibrant splendor.
