Barnes & Noble has Starbucks, Borders has Seattle Coffee, and Librerie-Coop in Bologna has...
Books, wine, prosciutto and homemade pasta.
And if you are still hungry, head up to the third level to the Osteria inside the bookstore.
Once finished, you can do some grocery shopping... and maybe even buy a book before you leave the store.
And before I forget, if you really want a coffee, capuccino's on the first floor (between the prosciutto and the Best Seller section).
