Spectacular art-deco coffee in the center of Porto...

Spectacular art-deco coffee in the center of Porto. From the architectural point of view it is incredible, but it has a "but" that can be important: the prices. A mineral water of half a liter is 4.5 euros, a coffee with milk 6 euros, a hamburger 16 euros (although it is good), a salad Caesar 18 euros. It is true that you are paying to be in that emblematic place, but it can be a bit excessive. I would give 4.5 stars.
