Vodka? Caviar? Live piano? Afternoon tea? This one spot serves many needs. Under the garden of Dale Chihuly flowers on the lobby ceiling, Petrossian is one of the most beautiful, if underrated, places to have a drink on the Strip. The bartenders here are seasoned professionals who not only know how to make a proper martini, but can give you a solid education on their selection of vodka, not to mention which caviar you should pair with each tipple. The pianists who tickle the ivories night after night are amazing entertainers in their own right; come in earlier for an elegant spread of afternoon tea. It’s open daily 24 hours.
