Orale is a red-, white-, and green-striped taqueria on wheels. For years, it has developed a devoted following of folks who flock to its locale on the S.W. 28th Street side of Douglas Park every Saturday and Sunday. The menu is tacos, tacos, and more tacos in their simplest, most authentic form: corn tortillas folded over meat. Some of the best include juicy barbecue lamb (barbacoa), slowly roasted pork (carnitas de cerdo), pork grilled with pineapple (al pastor), spicy chorizo sausage, and morsels of dark chicken that are smoky from the grill and imbued with well-marinated flavors. Orale also proffers popular Mexican parts of beef that are less familiar in the States, like lengua (tongue), suadereo (the fatty, rib-like beef belly), and cachete (cheek meat, a cut with cachet in fine-dining places). Tacos are slender, so you can eat a whole bunch of them (they are just $2.50 apiece). The only other option is a chicken-and-cheese quesadilla with sour cream, pico de gallo, and guacamole ($4). Cash only, and very well-spent.
