Fodor's Expert Review Plaza San Martín
This spectacular plaza is unlike any other in the city. It's surrounded on three sides by neocolonial buildings dating from the 1920s, the pale facades of which are lit at night, when the plaza is most impressive. Presiding over the western edge is the Gran Hotel Bolívar, a pleasant spot for a pisco sour. Even if you're not thirsty, you should step inside for a look at its elegant lobby. At the plaza's center is a massive statue of José de San Martín, the Argentine general who brought about the independence of Argentina, Chile, and Peru from Spain.
