Tips and Tricks for Brasília (Brasilia)

The other day, one of your IN members that just arrived here in Brasila asked me if I had any good tips for him.
There are always things that you wish you had known before... Tips and tricks you normally only acquire after living in a certain place for a while. Sometimes, we get them even ... too late?
So why not share what we know? We could make quite a big favor to others and even learn something new too.
Counting on your inputs :)))

Cheers
