Cake Batter froyo. That is the reason I'm a fan of Menchie's. Oh - and it's super clean, full of smiley employees and the biggest toppings station I've seen in a while. I topped by cake batter froyo with Butterfinger bits, milk chocolate chips and Kit Kat chunks. Oh yes I did.
It's a similar set up to other serve yourself froyo establishments...just be sure to gather some semblance of self control when you're creating your froyo creation. At $.42 per ounce you can indulge to just about any degree. And be sure to try the cake batter. Nom nom.
