I'll admit that I don't always try all the freaky foods that I find in the US. I would probably not fit in my bed if I did. This time I've tried it though! Just had an Andy's frozen custard carrot cake concrete!
It's basically a cup of really thick frozen custard with a big piece of carrot cake (with frosting and everything) shoved into it. It was actually pretty delicious. At least the first three bites (which was how long it took to get me full on it.....) I feel like I never have to eat again. And I got the SMALL size.
