From my perspective, I hope I never find the best one. It's so much more fun to try them all! Made with the local Key lime, it's not simply a cheesecake, it's a must-have for your visit. We stopped at the Green Turtle Inn (pictured in 360) restaurant the last time some of our team was in the Keys, it's one of the most well known spots for Key lime pie in Islamorada because they use a cashew base. I wish I took a photo, the pie didn't last haha If you've got a recommendation for a Key lime pie, a recipe, or just a story about trying to find one during your visit to the Florida Keys - please do share!
