Head to LA Cha Cha Chá for a taste of one of Mexico City's best bars this weekend. On Friday April 29 and Saturday April 30, Licorería Limantour—also named as the sixth best globally by the World's 50 Best Bars—will pop up on the Arts District rooftop from 10pm to 2am, walk-ins only. Limantour bar manager Eduardo "Yayo" Nava Mendoza will be serving a special pop-up menu plus the bar's classics, including the taco-inspired margarita al pastor (fresh pineapple juice, cilantro and green chili).
