Located in Arnold, 21 Rock Bar and Grill is surrounded by thick forests, farmland, and not a whole lot else. 21 Rock has been around for thirteen years and includes a spacious stage and dance floor, six pool tables and the "best priced drinks in Jefferson County" within 3500 square feet. Although it used to be a rough biker bar, and still a stop on many bikers' run, regulars promise 21 Rock is safe and comfortable. (Just think of those big, tough bikers with hearts of gold and "MOM" tattooed prominently on their biceps.) In fact, 21 Rock was the top donor for the March of Dimes three years in a row and regularly participates in other charity events. Friday night is ladies (and gentlemen) night at 21 Rock, with $10 rail and drafts. They also have regular bucket specials -- and famous hot wings.
