Learn Dutch: Zullen we bij de borrel aanschuiven, zodat we kunnen bijpraten? - Shall we join the drinks, so that we can catch up?

Zullen we is used to make a proposal or suggestion in the form of a question, just like "Shall we...?" in English. Laten we means "Let's..." and is used for statements, not questions. Since this sentence ends with a question mark and asks for the other person's input, Zullen we is the right choice.

What exactly is a borrel?

A borrel is a highly typical Dutch social gathering with drinks and snacks (often involving cheese and bitterballen). It translates loosely to "having drinks," but it is a specific cultural institution, most famously seen in the vrijdagmiddagborrel (Friday afternoon drinks with colleagues).

What does aanschuiven literally mean?

It literally means "to slide up" or "to push up." In Dutch, aanschuiven is a very natural and common way to say "to join" a group, a table, or a meal. It gives the cozy imagery of pulling up a chair to sit with others.

Why are both kunnen and bijpraten pushed to the very end of the sentence?

The word zodat (so that) introduces a subordinate clause. In Dutch subordinate clauses, all verbs are sent to the end. Here, the modal verb kunnen (can) and the infinitive bijpraten (catch up) stack together at the end of the clause.
