Fada cola

Fada Cola is a locally distributed cola soft drink produced in Marseille. The name "fada" is the Marseille version of the French word "fou", meaning "mad".
The catchphrase of the company is: "Qui ne boit pas Fada ne vient pas de marseille!" meaning "If you don't drink Fada you're not from Marseille." It is thus playing on the local factor, which is a very good selling point since every Marseillais is extremely proud of his hometown, and as a result, currently, the company is selling 1 Million units per week.
