I have stayed in a lot of US based Hampton Inns, Holiday Inn Expresses and Best Western pluses recently and the free hot breakfast they offer is mostly the same. Usually you get poor quality sausage patties, scrambled or boiled eggs, sometimes bacon, waffles or pancakes, cakes, cereal, fruit, juice, tea and coffee. It is never something I feel I would pay for.
You rarely get anything like eggs/omelets made to order in any of the mid level chains. The food quality in all the free breakfasts is pretty average at best.
