Souplantation is a United States-based chain of all-you-can-eat buffet-style restaurants. The first Souplantation opened in 1978 in San Diego, California, where the company is headquartered. The company was incorporated as Garden Fresh Corp. in 1983. The company went public in 1995 but was taken private in 2004. Outside of Southern California, Souplantation operates under the name Sweet Tomatoes. The company is owned by Garden Fresh Restaurant Corporation.
The first Souplantation restaurant opened on Mission Gorge Road in San Diego in 1978. It was the idea of Dennis Jay who was a bartender at the Bull & Bear in El Cajon. He had a dream and talked with two friends of his. One was an attorney and the other a bail bondsman. This restaurant and a second one were purchased in 1983 by Garden Fresh Restaurant Corp., founded by Michael Mack to operate the chain.
The company has expanded across the west and southwest and has locations in several Southeast states including 28 restaurants in Florida. They also have stores in Illinois, Missouri, Kansas, Colorado, and Utah. All restaurants are company-owned.
In 2005, an affiliate of the private investment firm Sun Capital Partners purchased Garden Fresh and with it the restaurant chains. As of 2012[update] the company had 112 restaurants in 15 states and claims to have served "300 million guests since 1978."
