Visited in October for my anniversary and was thrilled to see a man walking down the strip with a Garretts bag! I quickly checked Google to find where the shop was (At the Miracle Mile of shops - also great fun to visit). The popcorn was fantastic, and almost as good as the Garretts in New York, which is where I have always gotten it or had it from.
Fabulous popcorn, you MUST try the Chicago Mix, but a small bag of the sweet caramel with cashews would be good to try, too. Enjoy!
