Chicago’s dining scene is full of surprises, like this fact: The city’s very best al pastor taco is served at a pan-Asian restaurant. It’s true: Here, Iker Torres slices deeply flavored marinated al pastor off the trompo right into tortillas, and garnishes it with pineapple, cilantro, and onions. Tip: They’re just $1 apiece on Mondays. $1.50. 3823 W. 31st St., Little Village
