At Shooters Grill in Rifle, the award-winning barbecue comes with a gun on the side. The restaurant’s waitstaff, while serving brisket and cornbread, wear loaded and holstered sidearms. The fact that both the food and the servers pack heat has made the eatery famous around the world, drawing diners from overseas and vacationers who will drive in from Canada. Rifle is on Interstate 70 between Glenwood Springs and Grand Junction on Colorado’s Western Slope.
