It would take weeks to explore all of the delicious Mexican food hidden away in the nooks and crannies of the city of Richmond — at gas stations, tiny mercados, and roadside stands. But here's one of our favorite secrets: Norma Meat and Deli, a Salvadoran-Mexican takeout counter located in the back of an otherwise nondescript convenience store. Here, Norma Muñoz dishes out comically oversized burritos and wonderful, crisp-edged pupusas seven days a week, but she saves her homiest, and most delicious, dish for weekends only — one of the tastiest bowls of menudo you'll ever have the pleasure of eating. Her version of the classic hangover cure features a deep-red, subtly spicy broth; tender beef tripe; and patas, or beef feet, cooked slowly on the bone to add both a deep meaty flavor and soft, gelatinous bits that are prized by true connoisseurs. Bring your order of menudo home, or pull a seat up to the counter and enjoy it right in the back of the store. Either way, this is a soup that'll warm you up from the inside.
