What do Chris Rock, Jay Mohr and Todd Glass all have in common? Besides being some of the biggest names in comedy, they've all headlined the world-famous Improv Comedy Club stage at Harrah's Las Vegas. Each week, three new comedians take the Improv stage for a Sin City-style comedy show that's been voted Best Las Vegas Comedy Club for four years running. Stick around after the show as the comedians will often host informal meet-and-greets, sign autographs and sell merchandise. It's a great way to catch some of the country's top stand-up comics along with tomorrow's next big comedy stars. VIP tickets include preferred seating.
