Exactly, I frequent the two Starbucks (I am not a lover of coffee and like their frappes) in Devoto one in the shopping and the other on Beiro at the Meglaton. I have never seen another English speaker in any of these locations. I would say a select few Starbucks are making their money from tourists. There are no tourists in the barrios around me where there are Starbucks.You must not be from Buenos Aires as Starbucks is 99% argentinian customers . Most older cafes are closing down due to the change of the marketplace and customers evolving tastes .
I think some people are out of touch and think 16-25-year old Argentine's want to sit in an old coffee shop or cafe. They want Starbucks and/or another modern place and are driving the company's expansion, not tourists.
