Drink absinthe.

Absinthe lore is dominated by Paris' intellectuals and Prague's revolutionaries – most of them sliding toward madness – but you can now get the high-proof alcohol made with psychotropic wormwood extract stateside. At Comme Ça, an alluring new farm-to-table slice of Paris, mixology reigns so supreme that custom cocktails – including those fashioned from the green stuff – bear their on-site creators' bylines. Famed artistes Vincent Van Gogh, Ernest Hemingway, Pablo Picasso, and Oscar Wilde, among other absinthe imbibers, would approve and envy your absorption of the culinary and aesthetic pleasures on Comme Ça's lofty patio. It's a genteel bit of shade that rather fittingly offers the city's best view of the faux Eiffel Tower outside the Paris Las Vegas Hotel and Casino.
