If you're in Sintra, this is an absolute must. It's a really cute café with a very typical Portuguese retro vibe. The food is pretty good, as is the coffee, but this place is all about the experience: appreciate the décor, people watch out the window. It's particularly cosy when the weather outside is less than ideal for sightseeing.
Av. Doutor Miguel Bombarda, nº6, 2710-590 Sintra, Portugal
