I can't speak to the area that you are visiting as far as Key Lime Pie goes. When I have been there I don't remember seeing the pie for sale. A google search will show you a lot of good places in Key West, and some of them ship. You have several other options. One is to make it yourself. It is easy, if you can find the right kind of limes ("Key" vice "Persian"). You can also go to the frozen section at your supermarket. I like www.mariepies.com/product.php?cat=Thaw
and Serve Pies&prod=Key Lime Pie The thaw and serv product, though not as good as the real thing in Key West, is far superior to some of the junk I have seen in restaurants around here. (for some reason I can't link directly to the Key Lime product. My link gets you to the Marie site, but you will have to move to the "product" section yourself). Have a fun trip!!! BTW, if you dp a search of the "Restaurants" section of this site, you will find some kool places where you are going.
