I don't know, I still see all the older cafes packed to the brim as well. Likely because they also serve full meals and have better prices for what you're getting. The newer swath of Argentine cafes are also incredible because they're paying attention to the coffee beans and how they prepare each order. I think there seems to be a spot in the market for all of them at the moment. I haven't seen the classic Argentine cafes losing that much business to Starbucks. For me, Starbucks is the least exciting of the lot. Mediocre coffee that costs too much and an environment that isn't that inviting to inhabit as well as highly processed tasting foodstuffs. Both the classic and newer independent cafes seem to be going strong. Mcdonalds didn't put anyone out of business but they're also always packed. If anything, they created independent burger joints that rival it, all around town. Also, have to take into consideration that a lot of expats and travelers patron Starbucks and similar chains because they're familiar and easy for someone who's just used to that brand back home and wants a quick fix of caffeine while cruising around the city.
