No one ever made it to a second shake! It's one of those things that sounds fantastic--ALL THE MILKSHAKE YOU CAN DRINK! but in reality, very few people can do it. Great marketing.
This! But, I can only eat so much food at a time and a milkshake is VERY filling to me - one is almost more than I can handle and still eat some food But, it does sound good - so they play it up
We ate here in August 2011. They had the basic flavors plus an additional one. We were on the dining plan and it was covered as was my super sized diet coke. I was super happy I got one I was dying of thirst that day, although I acted like dh was the thirsty one. I got about half way through it, I think it was about 64oz.
When we went the last time I got two of them. I took my dessert to go. I knew that I wouldn't be able to finish the second shake but would be able to take what I didn't finish to go. I had the chocolate and strawberry and they were both great. This trip we will not be on the DDP so I will get two again. I didn't know they had other flavors so I will be sure to ask this time.
One time we went the flavor of the day was blueberry the last time we were there (September 2011) the shake of the day was caramel. My husband finished one and was offered a second. He could only make it about halfway into the second.
