We stopped here on our road trip. My 13 year old son said this was his favorite stop, and we had a lot of stops. Very interesting. There is a lot of walking, which was fine for us but if you have trouble walking this would be tough as some of the walking is in gravel to go from building to building. There were several exhibits that were closed for renovation so that was disappointing.
We stopped on our road trip and the food was good. Not a huge choice for picky eaters like my kids. Staff was nice, but I wasn't hugely impressed. We were there late afternoon, so it wasn't busy but the servers weren't attentive. Maybe all the reviews I read I hyped it up too much.
Nice place to get out and stretch after being in the car. We love finding unique places to visit and this was unique.
