The answer to the question depends on the wording of the articles of incorporation, the bylaws of the corporation, and any shareholders' agreement or voting trust agreement that may exist. Your friend should consult an experienced business lawyer in her area rather than relying on second hand advice from an online legal forum.

Restaurants are extra-tricky when compared to other businesses due to the additional permits and licenses involved (e.g., liquor license, food and beverage license, etc.). The corporate bylaws will control the corporate governance, and where there are gaps, look to the statute.
