I encountered this at the local grocery store. In case you can’t tell by the label, this is a chocolate cake made in the shape of a hamburger (complete with little white icing dots for the sesame seeds on the bun). Those are “french fries” on the left: they appear to be made from bread cut into rectangles and darkly toasted. I believe the “ketchup” is actually red icing.
No, I didn’t buy one (they had several of these, in both chocolate and white flavors): it was $20, and not something I’d eat by myself. Frankly, it makes me kind of bilious.
