Review for Mustang Sally's Review For Hamburgers Restaurant Google User Mar 21 '18 at 6:13 I drove up to Lewis's in a snow storm, ready for a warm dining room and a delicious cheeseburger. On both counts I was not disappointed. The wait staff was unbelievably friendly and efficient. The cheeseburger was part outstanding and part heavenly. A thoroughly enjoyable experience. Absolutely one of the best Cheeseburger in the Black Hills. View full site to comment or like
