For nearly a quarter century, the Coffee Cup has been synonymous with good eating and a sense of community. California transplants Al and Carri Stevens first fired up the grill in 1984, and decades later, in a new location five storefronts down, they’re still at it — now with the help of their grown children, son, Terry, and daughter, Lindsay. At the Coffee Cup, customers are considered family. “This restaurant means so much to Boulder City — the whole family does,” said longtime regular Bill Burke, a retired National Park ranger. More than a restaurant, the Coffee Cup in a little slice of western culinary Americana. Al’s pork chili-verde omelet, which celebrity chef Guy Fieri featured on his Food Network series “Diners, Drive-ins and Dives,” and the tall-glass Bloody Marys served with a thick wedge of bacon as a stir-stick, have given the Coffee Cup a national reputation as a stopover for RVs and SUVs en route to the nearby Hoover Dam.
