Aside from the fact that I think JJ will be bored out of his brains after a few weeks in RaymonRAB kitchen ( which defeats the purpose or suggests it's all a lie ), then according to your theory the fourth series of the restaurant will have nine couples with little interest in food, little cooking experience and no FOH experience but good business ideas competing to open a restaurant.
Well that's fine, but it's a different show to the one we all knew and loved and should be reformatted and rebranded as a different show, as this years should have been, so that the couples and viewers are not mislead and left feeling insulted by the result.
