We definitely spent a lot of time here on a cold day and had a great experience. There's so much to do, and so many shifting themes from one room to the next, it's like visiting several different museums in one building. As goofy as it sounds, the section on the Heinz company and its ketchup (et al) was among the best parts of the whole thing. I personally also liked the trolley that was on the first floor. Full-grown adults (with no children in tow) having a fun, educational, somewhat silly time - the photos we have all show us with very big smiles.
