Ricker’s exemplifies the class of regional c-stores whose industry leadership makes the chain feel larger than its store count would suggest. A longtime innovator at the fountain, Ricker’s began rolling out premium, brewed-by-the-cup coffee to all of its stores a couple years ago. Stores also now offer cappuccino, iced coffee and frappes, along with different flavors of syrups and creamers. All machines use reverse-osmosis water filtration.
