The company operates 18 breweries under the name Rock Bottom Restaurant & Brewery. These breweries are located in several states, with five restaurants in Colorado, five in Illinois and one restaurant each in California, Florida, Maryland, Massachusetts, Minnesota, Pennsylvania, Virginia, and Wisconsin. The store was renamed Rock Bottom after someone pointed out that they were "building at the bottom of the rock," which was Prudential's slogan at the time. In 2000, the Boston-based Brew Moon Enterprises Inc. filed for bankruptcy and sold four of its five restaurant-microbreweries to Rock Bottom. In 2009, the La Jolla location in San Diego won a medal at the Great American Beer Festival, and in 2012 they medaled at the World Beer Cup. Rock Bottom Restaurants won Brewpub Group Brewer of the Year award at the 2013 Great American Beer Festival (GABF).
