at PDT in new york city - from their website:
Barsol Pisco, Aperol, Lemon and Grapefruit Juice, Clear Creek Kirschwasser
Flatiron and Clover Club owner Julie Reiner created this drink when she returned from a tour of Pisco distilleries in Peru. She mixed Aperol, a low
proof, bright orange flavored Italian aperitif with Pisco and a rinse of Kirschwasser and named it after the city of Cuzco, situated just outside the ruins of Machu Picchu.
