Fill up on the exotic (tripe soup) or the familiar (tacos) at this bustling, family-run restaurant in the heart of Pilsen, Chicago's Mexican neighborhood. Big tables are often filled with large groups, lending a fiesta feel to the scene. Fans love the authentic food, including chilaquiles (tortillas with salsa and scrambled eggs) for breakfast and dinners of shrimp fajitas, chiles rellenos, and barbacoa (braised beef served with refried beans). Brush up your Spanglish; not all servers are fluent in English, though all are welcoming to newcomers. To wash it all down, order a tall glass of horchata, a milky, cinnamon-flecked rice beverage, or bring a couple of beers; Nuevo León is cash-only and BYOB.
