Inspector General Overanixius decides that since the Gauls of Asterix's village can't be subdued, they should be isolated from the world, and has a giant wall built around the village. Asterix declares that not only will he escape, but also collect special foods from different spots in Gaul; if he succeeds, Overanxius will take down the wall. With Obelix with him and the rest of the village as a diversion, the heroes make their break. What follows is a mad run around Gaul as Asterix and Obelix dodge Roman patrols. Eventually, they complete their rounds and return to the village to serve their
special to Overanxius; an uppercut!
- Continuity Nod: References to The Golden Sickle and The Gladiator are made.
- Early-Bird Cameo: Early on, a small, white dog with black spots starts following Asterix and Obelix around. Coincidentally, the next album would be the debut of Dogmatix.
- Hero Stole My Bike: To escape the Romans, Asterix and Obelix have to hijack a bystanders boat.
- Historical In-Joke: A native of Massilia (Marseilles) threatens a Roman patrol not to disturb their bowling game or else there will be blood on the streets, riots, revolution - "we're thinking of writing a song about that".note
- Honest John's Dealership: A used chariot dealer sells Astérix and Obélix a spanking-new ride with a strong black stallion... only problem is, the chariot falls apart within a few minutes, and the strong black stallion turns out to be a weakly white horse painted black, its paint washing off when it starts to rain.
- Lost in Translation: One of the reasons Asterix and the Banquet was the fifth Asterix book to appear in French but the twenty-third to appear in English was the translators' concern that the jokes based on French regional stereotypes (such as the inability of Normans to give a straight answer, the absurdly labyrinthine nature of Lyon's streets, the impossibly long traffic jams which stretch back from the Côte d'Azur at the beginning of every summer, the hot-blooded nature and penchant for exaggeration of the locals in Marseilles, etc.) would make little sense to audiences outside France.
- Shout-Out: The original French title (Le Tour de Gaule) and the central plot are allusions to the Tour de France, with Obelix's bag referencing the yellow jersey worn by the leader.
