I saw a mechanical bull in the faux redneck bar upstairs at the P&L district when we were down there the night the ISU women lost this year. I could swear I saw one drunk soil his pants while being thrown from the bull (and not "soiling" them in the FRONT, IYKWIMAITTYD), but I couldn't be 100% sure because of the lighting.
Bazookas is probably a good choice based on their location. I'm not current on the KC scene, but we went there during the tourney in '98 as a bachelor party for my college buddy "Rambill" who got married later that summer. 12 years ago, the employee quality there was very much "acceptable". Not up to the standards of the Penthouse club in Dallas, but better than your average Polk County strip club.
I think you'll have to do a flyby at Kelly's, just to have one of those big waxed paper cups of beer for nostalgia's sake, but don't plan on doing much partying in Westport. The P&L district has hit Westport HARD.
If you're down with BBQ, I would suggest that you visit Oklahoma Joes over on the Kansas side. It's just off Mission, and you've got to LOVE a BBQ joint located in a gas station.
One thing you need to think about, Chris: Deputize one of your friends as your "party cop". When we were in Dallas for the last tourney down there, my buddy "Hogfarmer" let himself get dragged upstairs to the Champagne Room. Two hours later, he was in a heated "discussion" with the bouncers after they caught him trying to pull a "dine & dash". I don't know exactly how much he charged to his Visa that night, but I'm pretty sure that you could at least buy a pretty crappy car that barely runs....or maybe a small herd of livestock.
The Most Important Thing? Have fun & enjoy the company of your buddies.
