Hola Cariba. I agree with Bobby Burgers. Right now it is about saving money, I'm afraid, even in the most affluent neighborhoods. With summer tourists gone, many expats moving country, and locals pinching pesos, empanada shops are not making enough money. I talk with people at the supermarket, they tell me about the changes they've been making to try and save money: eat out a lot less, make empanadas, pizza and tartas at home (to keep their kids from ordering food), buy cheaper cuts of beef.
In the past couple of months, the Coto in my neighborhood has been selling a lot more tapas para empanadas and tartas than back in October.
