Stravinskij Bar at the Hotel de Russie
This bar may be the best place in the city to sample la dolce vita. Celebrities, blue bloods, and VIPs hang out in the gorgeous Piazzetta Valadier where cocktails are well above par. There's also a selection of coffees, teas, healthy smoothies, and a full food menu if you need to refuel. It's especially popular for aperitivo, when canapés are served alongside the drinks.
