Admittedly, I have not checked out the more gussied up spots like Sol De Mexico nor Fonda del Mar. Also, Frontera nor any of the Bahena ventures have done much for me either- no mashed potatoes with my mole please. I also don't like to pay for salsa. I am a fan of sometimes overlooked
Mundial Cocina Mestiza in Pilsen, but I don't approach a meal there as a purely
Mexican experience. They do, however, make fantastic hand made tortillas and some of the more Mexican leaning menu items can really hit home, like the wonderfully complex Tamales Judios, the authentically Oaxacan, Quesadilla Campestre, and the Camarones Diabla augmented with wine, bacon, and butter, while retaining a blazing chile de arbol- fortified bite. But to answer the question of "best Mexican restaurant" I would proudly answer- there isn't one! We are so blessed in Chicago to have such a span of regional Mexican cuisine that this inquiry can be indexed into "best Michoacan food" or "best Yucatecan food". So my regional favorites, which are also board staples would be:
Cemitas de Puebla for Pueblan cuisine (cemita de milanesa por favor!),
Xni-pec for Yucatecan (which has introduced Chicagoans to many surprising delicacies such as rellano negra and papadzules), and
La Oaxaquena (which doesn't offer certain Oaxacan staples, like tlayudas or tasajo, but makes up for this with fantastic moles and conejo adobado- and they do have chapulines, fried grasshoppers for request from time to time!) Furthermore, Mexican dining in Mexico can have an informal approach with street vendors or taquerias specializing in specific dishes, which offer refined renditions of each particular speciality. In Chicago, we are also presented with such precise preparation, probably best represented on 18th street in Pilsen with carnitas spots-
Carnitas Don Pedro and Carnitas Uruapan and birria spots like
Birrieria Reyes de Ocotlán. Also, a number of taquerias on "carne asada row"- on Ashland between North and Chicago offers up the best in charred steak tacos and my favorite spot that offers both my favorite tacos asadas and tacos al pastor is the taqueria formerly known as
Carniceria Leon. The best way to graze through all of these regional specialties and the most authentically Mexican eating experience to be found in the city is a day trip to
Maxwell Street Market, where you can eat tamales Oaxaquenas, tacos de cabeza, and quesadillas de huitlacoche all in one outing. So maybe our best Mexican restaurant isn't a restaurant at all!
