Ashal, 

As noted in wordreference ‘escargots’ is (almost) always in plural (surtout pluriel). Although you can certainly refer to eating one escargot, or having come across an escargot you didn’t like, that would be an uncommon situation. Much the same as in English for ‘snails’. 

By the way, ‘j’aime les escargots’ in the positive and je n’aime pas les escargots’ in the negative, are the correct general expressions for liking or not liking escargots. 

See the link ‘note’ regarding definite articles with aimer.

 Du/de la/de l'/des all become de/d' in negative sentences (French Partitive Articles)

Which lesson are you referring to ? Rightly or wrongly, without the link, this looks like a homework question.

Yes without link . Just wondering why is with pluriel.

Bonjour Maarten, merci beaucoup pour l’explication. Maintenant, Je comprends!
