Italian pastry
Italian pastry, you can find the authentic Italian recipes, such as puff pastry recipes, in any Italian bar for breakfast.
The puff pastry recipes are another typical Italian product. When you enter in an Italian bar in the morning, especially between 8.00 and 9.30am, you may find yourself sorrounded by the wonderful aroma of freshly baked pastries.
It is pretty simple, but needs ample preparation time. Bars often buy pastries from a typical bakery or, sometimes, frozen ones that are baked in the bar. They are usually displayed in a small open shop cabinet on the counter and you're free to choose yours without asking to be served.
The Italian breakfast is often coffee/cappuccino and Italian cornetto. Most bars have the pastries on display in a self-service china cabinet, where you enter, ask for your coffee or cappuccino and take he pastry for yourself.
The most common one is cornetto, the Italian version of French croissant, presented in three main versions: unfilled, with cream or with fruit jam. Another choice is the ciambella, the Italian fried bagel. 
Italian customs
As I have told you, elsewhere on this site, Italians have many customs and it's often difficult to find pastries  in a bar during the afternoon, even if they would be wonderful for a quick snack.
But it is considered as breakfast, and so the bars buy or cook the quantity that serves for the morning. So, remember, you'll find always fresh pastries, but if you arrive around 11.30am you may find them finished!
I personally love to have breakfast, all kinds of breakfasts and so I can say that the Italian one, comprising cappuccino and cornetto is really good. The "not so sweet" taste of the pastry is perfectly matched with the cappuccino and gives you that feeling of satisfaction!
Each breakfast is suited to the local food culture. Italian breakfasts are not as rich as American or English ones, as Italians are supposed to have lunch at 1.00pm.
But, after breakfast, there are many other occasions to eat Italian pastry in general. I do not mean cornetto only, but real sweets or desserts .
There are some traditional Italian pastry recipes that are strictly seasonal, such as panettone, Colomba (at Easter time) for example.
