Pigs and chickens and goats? Oh my! This Restaurant Impossible takes chef Robert Irvine to rural Pipersville, Pa., and Mamma D's, a place that is part restaurant, part vineyard and mostly petting zoo. Owners Luigi and Liz Desiato are all over the place with ideas -- they have a vineyard, a farm stand, a wine store, a petting zoo and, of course, the restaurant. Robert is confused by what he sees and can't get over the smell, the animals and the clutter everywhere. Could this mission prove to be too much for Robert?
