Realizing that not every customer could, should, or would want an entire horseshoe for every meal, enterprising cooks developed the ponyshoe.  The ponyshoe is simply a smaller version of the horseshoe.  On a typical pony, you get one piece of toast, one piece of meat (some places serve two with a horse) and fewer fries.  The price is usually about $1 less for a ponyshoe than for the same type of horseshoe.  At many restaurants, a ponyshoe is server on a round dinner plate and a horseshoe is server on an oval platter.
