There’s a reason that Zona 10 in Guatemala City is called Zona Viva, or the lively neighborhood. Allegretto, a restaurant, bar, and dance venue with a self-described "European ambiance," is part of that reason. During the day, locals pop in for coffee on a lunch break. In the evening, you might see them again sipping a cocktail on the patio during a convivial happy hour. Depending on your mood, you're welcome to a seat indoors or out for an espresso, wine, or a mojito.
