This is a great little museum if you're at all interested in shoes. I took my shoe-holic cousin here and we had a grand old time. I love the current special exhibition, "The Roaring Twenties: Heels, Hemlines and High Spirits". It's on until June 2012. I've been looking for a pair of t-stray shoes for years and I am totally in love with some of the ones on display.
It's pay-what-you-can with a suggested donation of $5 on Thursdays from 5-8pm. If you're ever only going to go once though, consider supporting this delightful museum with full admission.
