If you want to meet him there is a chance if your willing to stand around and you stand a better chance if you have a few people with you.
Kevin Dorff (yes the writer of Late Night Kevin Dorff!!!!) told us when we met him that Conan usually comes out the front door of 30 Rock on 6th Avenue. But he can sometimes come out the side exit by the NBC Store on 49th St. So if you really want to meet him bring someone with a cell phone with you and station one person at each door and if you see him call the other.
We developed this strategy while waiting to see him on Tuesday but unfortunately by the time we thought of it he had left... Ah well we met Kevin Dorff and Pender and LaBamba and we're going back to try meet him again. I have to show him my tattoo before I go home!!!!
Best of luck getting into the show and I hope this helps you meet the King Of Late Night. You'll really enjoy the show. It's amazing live!!!
