They are so yummy hu!!! Walmart sells Andes mints that look and taste exactly the same. The only difference is that Olive Garden's wrappers don't have Andes stamped on them.
You are referring to Andes Creme de Menthe Thin Mints!
And they are soooooo good!
You can order them online. Just do a search on them, and look for the best deals!
