While previously successful, the Mayfair has fallen on hard times, which Ramsay attributes to owner Jack's refusal to fire head chef Juan, awful hygiene standards (which results in Ramsay closing the restaurant down for the first day for an extensive cleaning), and insistence on filling much of the restaurant with useless junk. Ramsay initially sees Jack's son John as the right man to take over, but quickly loses faith on finding out that not only has the car hire business that John runs separately been a huge failure, he's invested €40,000 of his parents' money into it too. After forcing John to promise to shut down his hire business and eventually repay his parents, and getting Jack to get rid of his hoard, Ramsay renames the restaurant Jack's Chicken Shack and creates a new menu focused around fried chicken. The service that follows initially goes poorly thanks to John's poor handling of the order system, but he eventually gets the hang of it, and service is successfully completed. In his revisit, Ramsay is encouraged to find that the restaurant is still busy, Juan has been moved to barkeeping duties and replaced by a younger chef (also called Juan), and cleanliness standards have been maintained. However, he makes John write an IOU to his parents when he reveals that he hasn't paid them back any money yet. (thetvdb.com)
