Question

According to the lesson Vrai before noun means quite a.... where as Vrai after noun means true. So why are we using vraie here before cuisine when we want to say a true kitchen?

Accepted Answer

Cuisine here refers to the food, not the kitchen. This is a statement of opinion, not fact.
 Vrai before the noun here means real or true, as in authentic - a subjective statement.
Vrai following the noun here would mean true as in factually correct.
The lesson does not cover all meanings and uses of vrai - better to consult dictionaries for that. Because it so easy to use, I usually start with wordreference but if I want more authoritative answers, Larousse bilingual or français, Robert or the Académie-française dictionaries all have free online versions.  
Also, check the link for an overview - note it still doesn’t cover all moveable adjectives or nuances in meaning with position change.
