I was surprised to find that people from Argentina love to drink beer along with mezze like we usually do here in the Middle East. Maybe this was the result of the influence of Syrian and Lebanese immigrants on their cuisine.
But I think mezze includes more elaborated food; the typical picada includes cheese, cold cuts, olives, peanuts, bread, snack food and that's it. The things served are more similar to the italian antipasto, but the way of serving them (many small dishes distributed over the table) resembles the mezze.
