We got an Oreo shake, since I hate Chocolate and Strawberry. She hates Vanilla (though I prefer that one to compare shakes, since it's a good baseline that everyone will have).
Anyhow, the shake kicked a lot of ass, and was superior to any other fast food milkshake that I've tasted. My girlfriend said that it was nice to be drawn in by a commercial, and actually be impressed with the product. I agreed.
