Pop right into Paris Baguette, grab a yummy pastry and head up the stairs that are tucked away at the back of the shop. This takes you to a little hidden gem. There is a small space for patrons with several window spots overlooking the main Piazza.
It's much quieter than sitting in the main plaza and you can still log onto the Venetian/Palazzo complimentary WIFI. If you've ever been to Venice, it's much like Museo Correr Cafe where you can pay a little extra to enjoy your coffee overlooking St. Marks Square even without an admission to the museum.
