So neat! It's a small museum in the basement. But it's very clean and neatly organized. I was quite impressed with the number of mustards they had. Cute displays and kitchy signs make for an enjoyable (and free!) visit. You can donate a few dollars in a box, and while we were there you got 2 bottles of Grey Poupon if you gave $5 or more!
If you're into trying new flavors the tasting experience is a must. We were unsure as to the mustard tasting protocol and thought maybe they had flights similar to wine tastings. Actually, you get to pick any flavor in the room and try it! Now that's amazing! While we were there we tried the Champagne, Lavender, Apple, and even the Spreckers Root Beer mustard.
It's fun, takes less than an hour and is the perfect place to take the kids on a super hot day.
