This is a very particular thing in Italy... night time only bakeries!
They open late at night and bake away for both bulk orders (ie the briosches that you eat in cafes) and by detail (ie for hte general public). I was told by my friend Kekko who is studying in Bologna that there are chains of nighttime bakeries, but they work more like fast food joints, but the beauty of this place is that its made here right before your eyes. THey have everything from pizzas, to briosches, merengues, baba', cakes... and everything is delicious! you can even special order things from them for an occasions, and its all relatively cheap (you are buying direct from the manufacturer).
The only thing "negative" (aside from the opening hours... this place can get really addictive), is that the decor is spartan, and they only have vending machine drinks (water, soda bottles/cans, and a coffee machine).
Great even just to stop by at midnight to get a briosche for the next morning's breakfast... just stick it in the oven for a few minutes the next morning and MMMMMMMMMMMMM
looks like a basic cafe'/bar from the outside, but inside and downstairs, you can see the natural beauty, inside its a rustic style "brick and cave" locale.
During the day, lots of students grab lunch here, but its also a nice place to have a drink in the evening
a cocktail bar in a private garden right by the lake with tables outside and a romantic candlelit setting, its open year round, but its so much more of an experience in warmer weather (when it gets cold, only the indoor local is served).
I highly reccomend the sex and hte city cocktail, and every cocktailis 5 euro.
