Black Coffee

Circle K’s black coffee, from their Simply Great Coffee line, is a surprisingly smooth, full-bodied brew made with dark-roasted Colombian beans, offering caramel and mocha notes without bitterness. At $1-$2 for a large, it’s fresh-ground per cup and piping hot—ideal for a quick caffeine hit. It punches above typical gas station fare, but freshness dips if the pot’s old.
