Not in Kissimmee, but if you want to get the Tee Shirt again, well worth a short visit:-

In a city with so much to see and do, the main attraction for locals as well as tourists is Hard Rock Cafe Orlando. Located at Universal Studios Orlando in the CityWalk entertainment complex, this Hard Rock Cafe is the biggest HRC in the world. With large, statuesque pillars, it stands majestically as a Roman Coliseum of rock, and boasts more pieces of rock 'n' roll memorabilia than any other location. The site includes not only a vast, multilevel Cafe, but throw in Hard Rock Live Orlando, a 3,000-person concert/party venue, and you've got a winner. Come on down when you wanna rock!
