I'm running out of reasons to head to the Strip (especially considering the looming parking fees), but the Lego Store keeps on bringing me back to Fashion Show Mall. This is the only Lego Store in the area and they hold great workshops for kids (and sometimes adults) to enjoy. I remember a couple of years back they were letting kids build brick pieces that would be crafted to make a giant R2-D2. The thought of so many kids in such a small space does scare me a bit, but the employees do a great job maintaining the store and preventing chaos from dominating. If you're looking for unique brick pieces, you are better off looking at the online store, but they do have a Fill-A-Bag/Cup specials here that may be worth it depending on what you need. Fashion Show Mall attracts a lot of tourists, so the stock here can deplete rapidly due to shoppers buying a lot of items all at once.
