Overview:
The fourth installment of the comedy road trip series features Steve Coogan and Rob Brydon returning as fictionalized versions of themselves. Directed by Michael Winterbottom, the series follows these characters on their travels. In this season, Steve agrees to review six restaurants and brings Rob along for the journey. The series is characterized by the characters eating, drinking, and attempting not to kill each other. (Note: I need to reach 160-220 words. Let's check the source content again.)
Wait, the source material is extremely sparse.
