Cattleman's and Dark Horse are right next door to each other and have the same menu. We ate at Cattleman's the first night, and then the Dark Horse two nights later. (We thought we'd try the Dark Horse because of their terrific beer selection.) We ordered the exact same dishes (a filet, the buffalo roast, chicken strips, and shrimp), but what a surprise! At Cattleman's, the filet and the buffalo roast were both cooked perfectly, as were the two kids' meals. However, at the Dark Horse, not only did it take them twice as long to prepare our food, but both the filet and buffalo were so overdone that they resembled charcoal, the shrimp was pure breading, and the chicken strips (how can you mess up chicken strips?) were burned as well. The family sitting at the table next to us apparently had the same problem and sent all of their food back. The beer selection was fabulous, which it needed to be in order to gag down the food.
Also, the bathrooms were filthy, and in the men's room only one (of three) facets worked.
or some significantly better options, try: Alpine Inn in Hill City, Cattleman's, Ruby House in Keystone, or the Blue Bell Lodge.
