Gran Caffe Gambrinus is a huge ornate place that is mostly a coffee and pastry restaurant.  They do serve heavier food but most people seemed to be enjoying a pastry, coffee and the surroundings.  The place has been around for 150 years and was restored in 1890 when they brought in many of the paintings and statues. It has been visited by many celebrities over the years, like Ernest Hemingway, Sigmund Freud, Angela Merkel, and Luciano Pavarotti.  They are ready for lots of tourists as the menu is in about 6 languages.  The tables are small but there were a lot of them and a good sized bakery at one entrance where you could come and get pastries to go.  We tried coffee and a Sfogliatella riccia which is a shell shaped Neapolitian classic pastry that has tons of layers of buttery pastry.  It was fabulous but looking around the place was just as good.  It is eye candy.
