The neighborhood we live in is actually like the Pearl district of Buenos Aires.  It’s very trendy and it has a lot of travelers.  So I went for a long walk on Saturday to check out some other parts of the city.  I headed along Av. Cordoba towards downtown before meandering through the neighborhoods.  The city is fairly spread out with a constant mix of houses, apartment buildings, stores and restaurants.  You never have to go more than a few blocks to find the necessities: fruit shop, carnicería, panadería, etc.
