Looking for recommendations - aperitivo - park

Hello everyone!
I am looking forward to going to Palermo with some friends in June.
I was wondering if Aperitivo is a thing there, in the sense of getting drinks with complimentary food like cold cuts, cheeses or even other dishes. I don't mean snacks like olives, nuts or chips.
We really enjoyed this in Milan so I was wondering if it is also a thing in Palermo.
If yes, can someone maybe recommend some spots?

Also looking for a park or something else to just hang out, have a picnic and some drinks, play some games - does anyone have any recs?

Any tipps are appreciated, thank you very much!
