twenty or thirty dollars for lunch? where? at the Alvear Palace?
one of the best gourmet burger places in town, Delapiane Bar, has 200 peso special regularly that includes an amazing huge burger, fries, and a pint of craft beer. 200 pesos these days is EIGHT dollars, not thirty. There is no doubt you can spend thirty bucks on lunch. But there are tons of places you can spend under ten. Again, you gotta eat local. Pizza, pasta, chori's, burgers, empanadas- all are available for lunch quite reasonably. Another place I like to eat, the pasta place Salgados Alimentos, near Scalibrini, has its pasta main courses priced in the same range- 200 to 250, for Pesto Risotto, or Ravioles de Cordero, and usually 175 to 200 peso complete lunches. This is not some dive, its really interesting innovative food. I love their curry ravioles, for example. There are dozens of other restaurants I like with similar prices- 8 to 10 USD for an entire lunch, and its good.
