At the National Mustard Museum, you can taste ANY MUSTARD they have (at least as far as I could tell - they let me try like ten of them), and they have a lot of mustard. Additionally, this is (I am told by people who try to put me down) the only place where it is socially acceptable for me to eat mustard with a spoon. (Apparently I am not even supposed to do this in my own house, because it is "weird.") Also, there are hilarious signs everywhere and some awesome mustard merchandise. Now that this place is in Middleton, there is no reason not to go.
