In tonight’s episode, the F Word will be taking to the road. Best Chinese restaurant Sween Mandarin from Manchester and best Indian restaurant Lasan from Birmingham will be joined by the winner of the American category, Argentinian restaurant Santa Maria Del Sur from London. All three restaurants will be giving their all, competing for the chance to cook in the grand final at the F Word restaurant tomorrow night. Over the course of an action-packed hour of mouth-watering entertainment, Gordon will put them through a gruelling series of tests to find out who's really got what it takes to hit the big time in the restaurant world. The hugely ambitious Aktar from Lasan, laid back Ernesto from Santa Maria and bubbly twin sisters Helen and Lisa from Sweet Mandarin will be pushed to breaking point as plate after plate of delicious food is subjected to Gordon's scrutiny. First, secret diners will visit each restaurant and hidden cameras will help Gordon decide who should be the first to be eliminated. Gordon will then turn up the heat on the two remaining restaurants by descending on them with coach full of demanding diners. Finally, he'll throw the restaurants into the toughest culinary environment of all: he'll invite them to his flagship 3 Michelin starred restaurant, Royal Hospital Road in Chelsea, and challenge them to cook the dish of their lives for a group of specially invited diners. There are three restaurants but only one can go through - who will Gordon choose to go through to tomorrow night's grand final?
