The Rainbow Bar and Grill is a bar and restaurant on the Sunset Strip in West Hollywood, California, United States adjacent to the border of Beverly Hills, California. Its address is 9015 Sunset Boulevard. The bottom level of the Rainbow is the restaurant, The Rainbow Bar and Grill. Upstairs is an exclusive club called "Over the Rainbow". The Over the Rainbow consists of a full bar, dance floor, and a DJ booth. The restaurant is next to The Roxy Theatre and The Key Club. The restaurant was founded in early 1972 by Elmer Valentine, Lou Adler, Mario Maglieri and others, opening on April 16, 1972 with a party for Elton John. At the time, the word "rainbow" signified peace and freedom. It quickly became known as a hangout for celebrities of all types. John Belushi ate his last meal(lentil soup) at table #16. Fo
