If the fact Ghost Bar is only open two nights a week — Friday and Saturday — doesn't give you an idea of the exclusive vibe that the club is going for, the dress code just might. Don't show up wearing shorts, tennis shoes, a baseball hat or anything that may be interpreted as workout gear—or you’ll see your chance of being let in to Ghost Bar vaporize faster than a spooky apparition.

Chicago’s Ghost Bar may not sit above a glittery strip of casinos like the Las Vegas location, but who needs an awesome view when the people watching options are so plentiful? Located above the swank restaurant Nine Steakhouse, Ghost Bar is a place to see and be seen; and a place to be scene-y. The hip green and silver decor (which includes lots of rounded edges and circular-type furnishings) sets the clubby tone for Ghost Bar patrons, who can spend their weekend evening splurging on bottle service and munching on snacks prepared in Nine's kitchen.

The bottom line: It doesn't get much more trendy than this. However, if you're looking for an even more exclusive Ghost Bar experience, the bar can be rented out for private parties of up to 250 people.
