Learn French: Est-ce que tu veux goûter les fruits de mer ?

When using two verbs together, the negative words ne and jamais go around the first, conjugated verb. You would say: Est-ce que tu ne veux jamais goûter les fruits de mer ?

Why are there two verbs right next to each other (veux and goûter)?

Just like in English, when you use two verbs together, only the first one is conjugated to match the person doing the action (tu veux means 'you want'). The second verb stays in its basic dictionary form, called the infinitive (goûter means 'to taste').

What is the literal translation of fruits de mer?

It literally means 'fruits of sea'. In French, this is the everyday phrase for seafood. Note that it usually refers to shellfish, crabs, and shrimp, but not actual fish.

Why is it les fruits de mer and not just fruits de mer?

In French, you almost always need an article like les (the) before a noun, even when talking about things in a general sense. While in English we can just say 'taste seafood', French requires 'taste the seafood'.
