The same is true of Spain
and Spanish-influenced countries.
Apart from mere socialising, this is also an excellent way to check out potential future partners.
The equivalent in Australia, and I guess the USA, is to go wander around the nearest Mall. Which is my excuse to include this haiku that I wrote a while back:
Coffee at the Mall:
Of track pants and bad hair.
