The first East Side Mario's restaurant was developed and built in Aventura Mall in Miami, Florida. To expand the business on both sides of the border, it was necessary for Yesac to raise capital. To do so, the collective brands of Casey's, East Side Mario's, and Pat & Mario's merged with the Lime Rickey's brand from Toronto to become Prime Restaurant Holdings Incorporated in August 1989. Prime Restaurants has become a major force in the current Canadian restaurant industry largely in part from this acquisition. By 1993, Prime Restaurants had expanded East Side Mario's throughout the United States through an American subsidiary. Because of the high potential of this restaurant chain, the American subsidiary was later purchased by PepsiCo's Pizza Hut division (eventually sold ESM to Marie Callendar's 1997), and Prime Restaurants retained exclusive rights to the Canadian trademarks. As of February 2000, Prime Restaurants had re-acquired global trademark rights to East Side Mario's Restaurants Inc. On July 22, 2002, the parent company made an initial public offer for the Prime Restaurant Royalty Income Fund, allowing for public investing into the brand.
