The cheesy rajas, beefy desebrada roja, and peppery picadillo get top billing at Tacos Chiwas, midtown Phoenix's beloved Chihuahua-style taqueria. But it would be a mistake to leave without trying the restaurant's excellent frijoles charros. Whole pinto beans are simmered in a broth flavored with bacon, hot dog slices, onions, and fresh cilantro. The result is a velvety, richly layered stew that's a meal all on its own. Beans are a staple of most Mexican restaurants, but they're rarely as memorable and delicious as they are here.
