How does adding 'degli' in 2. change the meaning of 1.?
Sono stato al ristorante con amici.
Sono stato al ristorante con degli amici.
In my opinion
Sono stato al ristorante con amici.
stresses the fact that the people I was with were friends, as opposed to other "categories" such as family members, coworkers and so on.
On the other hand
Sono stato al ristorante con degli amici.
gives slightly less importance to the kind of people I was with and communicates two facts (I went to the restaurant and I was with friends) with no focus on a particular one.
"Degli" in this context means "a certain quantity of, some", so the two examples have different meanings:
- I went to the restaurant with friends
- I went to the restaurant with some friends
The change in meaning is analogous as you would have in English.
