Plain and simple: I thought Elisha's cheesecake was genius. If you're not from the Bay Area, the inspiration was the It's-It Ice Cream Treat, an oatmeal cookie ice cream sandwich all dipped in chocolate. They come in a variety of flavors, my favorite being mint.
Elisha's cheesecake follows this theme by having an oatmeal cookie crust and what would have been a hard chocolate shell (it was a very hot day and being brainiacs, we neglected to have the tasting in the shade). The cheesecake itself is espresso flavored.
There was little wrong with the cheesecake. Espresso cheesecake: Mmm.... Chocolate coating: Mmm.... Oatmeal cookie crust: MMM....
