Feel like wasting away in Margaritaville? The answer is yes, so come out to the outdoor Chicago Margarita Fest at Northerly Island. The Fest features a whole slew of margaritas from some of the city's best restaurants, along with food trucks from some of the city's best restaurants. And while you sip, enjoy live music, from artists like The Chics, Josie Day and Nina Katz. A fireworks show at dusk rounds out the day of drinking.
