Rudi Carraro was a bartender at London's Artesian Bar, which snagged the coveted top spot on the World's 50 Best Bars list thanks to a cocktail menu that "effortlessly blends modern innovation with a classic reverence and each beautifully designed concoction justifies its luxury price tag."

Now he's a global brand ambassador of Amaro Montenegro. His guest menu at Bvlgari's II bar tonight includes a Monte Mule (made with Amaro Montenegro), and a Caffe Martini (featuring Vecchia Romagna cognac).

Don't miss this guest shift by one of the globe's most renowned bartenders.
