Asterix and the Banquet written by Rene Goscinny and illustrated by Albert Uderzo
The ancient Romans decide to wall off the renegade village that is home to Asterix and Obelix. To prove that they can't be cut off from the rest of Gaul, Asterix makes a bet with the Roman leader--Asterix and Obelix will escape and get culinary delights from all over Gaul to show the Romans how great Gaul is. Or something like that. The plot is the thinnest ever, even by Asterix standards. The book has the standard jokes, punny names, and silly fights.
Overall, it's entertaining but forgettable. If you are going to start with Asterix, don't start here, there's lots of other better material out there (Asterix in Britain is still a favorite of mine).
