Across the street from the Hyatt is a crappy little "bbq" joint, called Kansas City BBQ. Don't go there planning to eat because the BBQ sucks. But it is the bar from Top Gun where Mav, Goose, Kelli McGillis, and Meg Ryan did the "You shake my nerves and you rattle my brains..." scene, as well as others. One of Mav's helmets from the movie is still in there, and the piano is still in there too. If you went in there without somebody telling you that the bar was known for Top Gun you'd probably never really figure it out because its not really an "in your face" thing. If you hang out long enough you will do NightTrain shots every time one of the trains goes behind the building. NightTrain shots suck, but they're only $0.25.
