If you're into the unusual you'll love this place. Even kids love it. There are so many exhibits you won't know where to go first. Tickets are pretty reasonable (around $15 per person) and the experience is one you'll talk about for days! My favorite is the Odditorium, weird at it's finest! The gift shop is stocked with all kinds of novelties, some are reasonable others are not. If you've never been, you've got to go at least once! It's right across from the Alamo.
PROS: Great place to spend a day off!
CONS:
