Or you can slum it on the price and go where size counts at Jimmy Buffett's Margaritaville at the Flamingo Hotel. Head to the sidewalk with the hordes, carrying your 20-ounce cash-and-carry glass of License to Chill, a heady blue-hued mixture of Margaritaville Gold Tequila, Bols Blue CuraƧao and the cafe's secret margarita frozen or on the rocks in a long, thin plastic glass for $7.50.
