About にする

にする is a structure that combines the particle (a location/target), with the verb する. It means to 'make/decide' something in a certain way. The nuance with にする is that the speaker has direct control over the outcome. This is where the strong feeling of 'choice' comes from. The noun that comes before にする is the thing that is being decided.

In this example, although the common translation is 'to decide', it is actually much closer to the slang expression 'to do (A)' in English. This means that the literal translation is actually 'I'll do a beer', or 'I'll make it a beer'.

Sometimes the particle is used instead of に. Although this has the same meaning, it changes the nuance slightly. When is used, it takes away the feeling of being a direct decision. とする tends to be used in more formal situations, but this is only because is less 'definite', so results in the phrase sounding less pushy.

If you were going to compare these two to an English equivalent, it would be similar to the difference between the following sentences.

- I'll buy a burger. (A burger is the direct target of 'buy')

- I'll go with a burger. (You aren't 'going' anywhere, it just sounds softer)

This grammar point may be used for more abstract nouns, and does not specifically need to be 'items'.

              DBJG has a useful distinction on the difference between にする and に決める which might be worth mentioning.

              hello @Jake!

              I got a review on this together with “shall” (ましょうか), but this item comes after にする, so I was a bit lost on that.
              is this an error? shouldn’t this only show up after I review ましょうか?

              Hey @mielke
              We will likely replace the sentence, by the way, if you tap on the ましょうか it will show the definition
