Brigham Young lived with one of his wives and families in the Beehive House during much of his tenure as governor and church president in Utah. The required tours vary; some offer historic house details over religious education, depending on the LDS docent.
The attached 1855 Lion House, which was home to a number of Young's other wives, has a self-service restaurant in the basement. Feel free to look around the dining rooms during mealtimes.
