Happened to be in the South Lawndale area and dropped by this newish little DF-style cafe down the street from Casa de Samuel.*
It's a bright, clean and cheery place occupying the corner storefront of the magnificent Marshall Square Theater, now a Mexican event hall called Apollo's 2000.
http://cinematreasures.org/theater/3500/ The restaurant looks out west over the broad boulevard, which at that place runs down Marshall. Apparently, not too long ago the space was occupied by a chop suey joint. Despite its location and very steady business from the neighborhood, it's virtually unmentioned on the Internets.
Los Corrales will resonate with posters who have spent time in non-tourist areas of Mexico, especially the DF, because it is what I would call "Mexican First World." 100% Mexican, not adjusted or watered down for US tastes, but also very professional, even slightly "corporate" in its look and feel. This place could clone itself in the Loop and do well. To me, this means almost nothing. I mention it for those who might shy away from shabby corner bodegas, all night taquerias, or grey-market vans.
The important point: the food is
very good based on my limited sample: twin quesadillas, one flor de calabaza, one mushroom. A lot of food for about 3 bucks each. The squash flower quesadilla stood out. Pristine fresh masa tossed on the griddle and filled with good cheese and terrific, chunky squash flowers cooked in a light tomato and chile broth -- not the straight-from-the can green sludge that is seen so often (though, being well-cooked I couldn't tell you exactly how the flowers started out). Also, while the masa had been pre-formed and was peeled from a piece of wax paper, it was top notch. My quesadilla was as a perfect Neapolitan margherita is to the average greasy slice of pizza. (Likewise, you must eat it immediately; this quesadilla doesn't travel.)
I observed hauraches and other antojitos made from that same masa, and also saw plates of great-looking guisados go by. NB, the permanent menu features breakfast (chilaquiles and beef deshebrada), plus some relatively hard to find items: eg, huitlacoche and carne en su jugo all the time.
At a time when "concept" Mexican street food stands are the rage, Los Corrales is a place to reset your barometer. I'm not suggesting that Corrales is head and shoulders above the many great corner Mexicans on this board, but it's too good to go without mention here.

*Also near the somewhat confusingly named Birreria Riveras [not GNR Reyes] de Ocotlan. I tried one birria taco, which was quite good (meat kept separate from consome and chopped to order, good commercial tortillas griddled, solid broth; not Zaragoza, so don't ask). I was also interested to see a new Acapulco-style place west of Marshall on Cermak: Atardecer Acapulqueno ("Acapulco Sundown"). Didn't stop in, but I'd like to think it has pozoles.
