SAVE THE DATE: HARD ROCK B-DAYOn June 14, 1971, the founders opened their own American-style diner in an old Rolls-Royce dealership and called it Hard Rock Cafe. They had a vision to combine music, memorabilia and all-American fare. Hereís a tip: To celebrate Hard Rockís birthday, they arenít buying themselves a cake. They are selling us burgers. For 71 cents. Head in June 14 starting at 11:30 a.m. for the classic Legendary Burger, its beef patty topped with smoked bacon, cheddar cheese, a golden fried onion ring, lettuce and tomato, served on a toasted brioche bun with seasoned fries. Oh, and hereís the clincher: The birthday party features a í70s disco theme with disco bands. Guests are encouraged to wear disco attire. Seminole Hard Rock Hotel & Casino Tampa, 5223 N Orient Road.
