In my opinion, the making of a good torta is all in the application of refried beans. Every torta should be made that way, and it just so happens that that's how they do it at El Rinconcito (The corner or little nook). There are two lovely ladies that run the place who seem to know the names of all the people that patronize it, which is always a good sign. We tried the milanesa (breaded beef) and ham, and the pierna (ham shank) both loaded with avocados, Oaxacan cheese, tomatoes, and jalapeƱoes, making every bite an incredible but messy experience. If you don't mind standing while you eat, then I highly recommend this little hole in the wall.
On the corner of Citlaltepeti and Amsterdam, in front of the glorieta (roundabout).
