The top 1-5 cannot-miss things in Buenos Aires?

I'm just coming back from Buenos Aires. I stayed in Recoleta as well. Here are a few can't-miss places:

- Palermo Soho: Palermo is a neighborhood next to Recoleta and "Palermo Soho" is a few blocks in Palermo with really special restaurants and coffee shops. One of the best restaurants is "La Cabrera" (http://www.parrillalacabrera.com.ar/)

- Calle Corrientes: Avenida Corrientes street is where all the theaters are. This is the main reason Buenos Aires receive so much latinamerican tourists.

- Caminito: Caminito is maybe the most recognizable street  in Buenos Aires, there you can find local shops, restaurants and tango. Caminito is located in "La Boca" neighborhood, which isn't a good neighborhood nowadays, so the recommendation is to go in a cab directly to Caminito, walk around and then grab a cab again to Recoleta.

- Centro Cultural Recoleta: As the name says, is located in Recoleta. It's kind of a theater and now they are playing "Fuerza Bruta" (http://fuerzabruta.net/), part theater and part party. A must go.

- Last tip is not a place but an App, download the iPhone/Android app called "Stay", Stay let you download the complete map of Buenos Aires so you can use it there with your GPS but without spending a dime. (International rates for using internet are huge, but GPS is free, just put your phone on airplane mode and turn on your GPS)

Moses,

If you have the opportunity to travel, do not stay so long in Buenos Aires and uses the time to visit other places in Argentina, which are much more beautiful.

But look here: Buenos Aires

Recoleta Cemetery is gorgeous.

-For local crafts and art, the San Telmo street fair on Sunday is great.

-If you're interested in Evita or history in general, the Museo Evita is very nicely put together.

-El Cuartito Pizza was really good. Ate there once, did carry-out another time.

-I heard (but did not get to experience) that Steaks by Luis is really great. Would love to try it if I ever make it back.

The  Recoleta Cemetery has to be one of the most impressive in the world.  Worth a half a day of strolling about.  The Confiteria Ideal is a place near the Obelisk to see locals gathering nightly for milongas, authentic tango gatherings, in the upstairs dance hall. Don't return a stare if you don't want to dance, or go early for the lessons. It was a location in the "Evita" movie. 

We took day trips to the delta region, Tigreby train(Linea Mitre), from the Retiro station, and rode the vaporetto taxis out to island to hike and see a very different  way of life.  La Plata, the state capital, was reached by a short bus ride to visit the  excellent Natural History Museum there. If your visit covers a Saturday, don't miss the street market in San Telmo, best place to choose a mate cup and straw to bring home.  The Zoológico de Buenos Aires ranks right up there with the world's best.

Anything you want to keep should be in your front pants pocket at all times.  Do not pull out your wallet anywhere in public, especially somewhere you might be expected to pay for something.  Pick-pocketing is a recreational team sport in Buenos Aires, and the national ethos is that if someone takes advantage of you, that's your fault. Accept that, and you will be fine. Our host in Recoleta cautioned that you couldn't really trust the maid service and advised against leaving valuables in the apartment.  Things will be stolen from your backpack, while you are wearing it! 

Cross-country trips should be accomplished by night bus, also from Retiro, the best way to travel in the world.  It's your accommodations for the night, often for less than a hotel, and it doesn't burn up your valuable trip days, getting you there while you sleep.  Iguazu Falls and the hot springs resorts in Salto, Uruguay  are within easy reach.  Have a choripan for me!
