Four stars for this fun and irrevrent shrine to the yellow condiment! (You gotta love a place that bills itself as the "home of Poupon U"!) The museum has a mind-boggling assortment of mustard from all over the world, including posters, magazine covers and advertisements. For those who prefer to put their wallet where their mouth is, the store has an equally stunning assortment, categorized by country and flavor. As the previous reviewer noted, you can sample just about anything they sell - a big plus.
