How to Say “Yum Yum” in French

Is there a formal and an informal way to say it?

miam miam is highly informal and is primarily used by children or when speaking to children in a playful manner. In formal settings, you should use more polite expressions such as C'est délicieux to express that something is delicious, C'est exquis to emphasize the exceptional taste of a particular dish or C'est succulent when a dish is mouthwatering and focuses on richness and savory appeal. For informal situations, you might also use C'est trop bon to say something is too good or so tasty, C'est super bon to add enthusiasm or C'est à se lécher les babines to describe incredibly appetizing dishes that literally make you lick your lips.
