The theme of cafe prices in BA has come up a number of times. I am writing this from Vienna. A very nice cafe here called AIDA (from what I can see one of the better ones - located in a part of town equivalent to the heart of Recoleta) charges the following: espresso 1,70 euros; average 2,60 euros for a piece of cake (nothing more expensive). This corresponds to 7,50 pesos and 11,50 pesos respectively. I routinely pay the same for coffee in BA and more for a piece of cake (usually stale). The coffee here is superb. The pastry is world famous. Last week I had a cafe au lait (large, not small) and a wonderful, fresh, delicious pastry in the Paris Gare de l'Est. The price was 4,20 euros (about 18,5 pesos) - higher than BA but not that much. The last I checked coffee and 3 stale media lunas at La Biela was 13 pesos. Either Europe has become cheaper of BA has become more expensive! I know some expats will cry foul but this is what I see with my own eyes. Even London was affordable, especially now that the £ has dropped.
