we did it in september.
the process is a pain, you have to order from the mercantile at the front of the park a few hours in advance, and then pick up over at the bakery in africa. it comes to about $9 per head.
if you are paying OOP, it's pretty cheap for sandwich, sides, dessert and a drink. however, if you are on the dining plan, it's not a great value. the sandwiches are pre-packaged (like you would buy in the efrigerated section of the convenience store) and come with a small bottle of water. you can get much more, and better quality food from any other CS restaurtant in the park.
