For any sort of curved, fan-like surface this illusion is present.  However, it can easily be seen in food like bundt cake and baumkuchen as well as fruits placed on plates.  Based on orientation and placement, oftentimes one slice of food will appear larger than the other, which effects the decision-making of the person choosing a slice to eat.  Because one appears larger than the other its value to the person looking at it changes.  When discussing things like cake-cutting, this can become problematic, since we often assume that the value of a slice of two homogeneous and equal-sized pieces should be the same for a single person, however the illusion might trick a person to evaluate one slice as worth more than the other.
