1/2 lb. of beef smothered with Applewood smoked bacon, ham, mushrooms, Cheddar cheese and a fried egg. Takes 2 hands, 2 napkins and 2 beers. Served on a pretzel bun with your choice of side. All beef burgers are made with the perfect blend of ground chuck and sirloin. Chuck contains enough fat to add flavor and juiciness. Sirloin provides tenderness, flavor and great taste. It is how great hamburgers are made.
