If you need a place to relax and kick back this is the place to go. Maybe you're looking for a casual chill party to throw, whats a better place than the top of a skyscaper! Always be responsible though!
To access the rooftop of the Inn Of Chicago just find the hotel on the Magnificent Mile. Hop onto the tiny elevators and climb to floor 22. From there you should be able to easily access the rooftop balcony. It is the perfect place to through a party!
