Hard Rock Cafe, Inc. is a British-American multinational chain of theme bar-restaurants, memorabilia shops, casinos and museums founded in 1971 by Isaac Tigrett and Peter Morton in London. In 1979, the cafe began covering its walls with rock and roll memorabilia, a tradition which expanded to others in the chain. In 2007, Hard Rock Cafe International (USA), Inc. was sold to the Seminole Tribe of Florida and was headquartered in Orlando, Florida, until April 2018, when the corporate offices were relocated to Davie, Florida. As of July 2018, Hard Rock International has venues in 74 countries, including 172 bar or cafe-restaurants, 37 hotels, and 4 casinos. On June 10, 2021, Hard Rock announced Lionel Messi as its Hard Rock brand ambassador as the company celebrated its 50th anniversary. History Cafe-restaurants The first Hard Rock Cafe opened on June 14, 1971, at 150 Old Park Lane, Hyde Park, Mayfair, London, under the ownership of two Americans, Isaac Tigrett and Peter Morton. Hard Rock initially had an eclectic decor, but it later started to display memorabilia. In 1978, a second location was opened in Toronto, Canada. The chain began to expand worldwide in 1982 with locations, among others, in Jackson, Tennessee, Los Angeles, San Francisco, Chicago, Paris, and Berlin. Hard Rock Cafe locations in the United States vary from smaller, more tourist driven markets (Biloxi, Pigeon Forge, Key West) to large metropolises (Houston, Philadelphia, Baltimore, New York City, Chicago, Boston, Washington, D.C.). Hard Rock Cafe typically does not franchise cafe locations in the United States. All U.S. cafes are corporate owned and operated, except for cafes in Tampa and in the Four Winds New Buffalo casino. However, in the transition of the Las Vegas Hard Rock Hotel property, originally owned and then later sold to Rank by founder Peter Morton, Morton retained hotel naming rights west of the Mississippi. When Morton sold his Las Vegas Hard Rock Hotel to the Morgans Hotel Group, he also sold those naming rights, which then gave rise to two US franchised hotels (without cafes) in Albuquerque and Tulsa. (The Albuquerque hotel no longer pays for the Hard Rock rights and reverted to its former name in June 2013.) Additional casino hotels franchised from Morgan's were subsequently opened in Sioux City, Iowa and Vancouver, Canada. A Hard Rock Cafe exists in Empire, Colorado, which was established in 1934 that is not part of the chain. In 1990,
