You basically get three comedians for the price of one. There is an emcee who does a short set, an \""opening act\"" comedian who does a longer set and finally the headliner who does a full set. I saw Graham Elwood who was great and Nick Griffin who was even funnier (and has a FML style of comedy that seemed to work better with those of us in our 20s-30s than with the geezers in the crowd). Of course how good or bad the comedians you see are will make or break the night. \n\nI went on a Tuesday and it was about 1/2 to 2/3 full (but this is Vegas so I assume most of us were there on vacation). We got buy one get one free tickets from a Harrahs coupon book you receive when you sign up for the free Player's Club card. Otherwise tickets are about $30\n\nOne final thing...beware that the drinks at the Improv are about the same size drinks you get from the cocktail waitress in the casino itself...they just charge you $9 for them! So if you are going to gamble at Harrahs before the show you might just want to get a few drinks and save your $$.
