In the first episode, after sifting through over 12,000 nominations, Gordon presents his two finest Italian restaurants. First up is Mennula, a traditional Sicilian restaurant in London. Sicilian-born head chef Santino opened his thriving business less than a year ago, and specialises in authentic, simple dishes from his homeland. The opposition is Casamia, an innovative restaurant in Bristol. Head chefs and brothers Jon Ray, 26, and Peter, 24, are the youngest chefs in Britain currently holding a Michelin star. Who will emerge victorious?

In the 2nd episode, after sifting through over 12,000 nominations, Gordon presents his two finest Indian restaurants, Bradford's Prashad and The Brilliant. Prashad is a family affair. The restaurant is run by Bobby and his wife Minal, who is the head chef, while Bobby's mother Kaushy was responsible for training Minal and now helps in the kitchen. Prashad was originally run by Bobby's mother Kaushy. She learned to cook as a girl in India, helping her landowner grandmother prepare feasts for the farm workers. When her daughter-in-law, Minal, arrived from India after marrying Bobby, Kushay encouraged her to start cooking as a way of finding her feet in a new country. The Brilliant Restaurant is a family-run Southall institution. The Brilliant is headed by owner, Gulu, whose son and daughter work for him in the restaurant. The restaurant was set up by brothers Gulu & Kewal Anand, who came to Britain in 1972 from Nairobi, where they ran a successful restaurant called Brilliant.
