I stumbled into this museum while walking around the Galleria mall. And it is quite a gem. It goes through the history of Hungarians in the US since the revolutionary war. I learned a lot while exploring the small exhibitions and old books. The various clothing and pictures tell an inspiring story of multiple generations of Hungarians. It is both a story of immigration and integration by a rich and powerful culture.
It is rather surprising to find such a museum in a mall, but it is probably the best thing in the entire Galleria and I think that this model of having a museum in a mall is actually quite a good idea.
