Chef Robert Irvine is in for a taste of nostalgia when he's challenged to fix an old-fashioned lunch counter located inside a family-owned pharmacy. Purchased by Tony more than 50 years ago, Lyon's Pharmacy of Elkton has been a staple in the tight-knit Maryland community, but Tony's daughter Marybeth, a pharmacist by trade, has been struggling to keep it afloat since her father passed away last year. With old, rotted floors and hours needed to restock the pharmacy shelves, Robert needs the full support of the community to pitch in and save a piece of their town's history.

Normally, struggling restaurant owners know well in advance when Chef Robert Irvine and his team are coming, but this is not a normal mission. To get a truer picture of the problems facing the restaurant, Robert ambushes the owners of Tornatore's Pizzeria in Orlando, Florida, and no one -- the owners, the design team, the crew, not even Robert himself -- knows what's to come.
