One of the things I forget about places that aren't Paris is that they don't have espresso everywhere. In most of the large parks in Paris you can get a cup of coffee to sip while you sit and watch the people or the birds or whatever it is you do in a public park. It's a lovely option to have, and I wish everywhere did it.
The train stations also for the most part have coffee machines, and most restaurants will sell you an espresso from a real espresso machine (as opposed to whatever the train station coffee is). Overall it's a very caffeinated place.
