This was an interesting novelty, to say the least. We were greeted by very enthusiastic employees when when entered the building.
The museum itself was an oddity, displaying thousands of old mustards collected from every state and a variety of countries. I had expected more on the mustard-making process than what there actually was.
There are hundreds of mustard options in the gift shop, all of which you can try before purchasing. There's guaranteed to be a mustard for everyone out there, whether it be fruity, spicy, traditional, tart, sweet, or more.
It is worth a stop, but don't expect too much.
