Don't expect high end or fancy, but do expect quick service, large portions, and good food. Pizza was VERY good. Lasagna was far too "doughy" for me - too many noodles and not enough meat. Great for groups and families. Mammoth lacks really good restaurants, but we'd come back to Giovanni's again. Kids love it.
