Try some of the local brews. Kansas city is home to some of the best beers I've had in the US. Boulevard Pale Ale is fantastic. Also eat some KC Barbeque, it's world famous
Fondest memory: Eating a 100 wing dinner at Hooters with a few of my Army buddies. We were almost sick after this endeavor.
Favorite thing: Go to any bar and have yourself a nice cold draft of BOULEVARD BEER--it is brewed in Kansas City and is great with a squeeze of lemon.
