Passage: The chain began to expand worldwide in 1982 with locations in (among others) Toronto, 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, etc.) to large metropolises (Houston, Philadelphia, New York City, Chicago, Boston, Washington, D.C., etc.). Hard Rock Cafe typically does not franchise cafe locations in the United States. All US cafes are corporate owned and operated, except for cafes in Tampa and 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. More hotels franchised from Morgan's are planned for Sioux City and Vancouver.
