A bad start (Tito wanted "migas" with is stake and got the answer that "migas" could only be combined with entrecôte... why?), continued with the disputed "migas" (that I ordered with... entrecôte) and that were more "açorda" than "migas" (after two weeks in Portugal you will be prepared to understand the difference).
After that, everything went well - the other dishes were approved, and lunch was good - until the end: credit card was out of work, what forced me to go to a close ATM machine.

Cheap and well placed
I can't say much about this restaurant, because I only had there a quick meal. The general idea was positive: the service was fast and gentle (I went late and there were only a few clients). Some starters (the cheese was very appealing, but I'm above 60...), the house wine was good, I ordered grilled sausages that were well served, and after coffee, I paid less than 10 €, however, the average price rounds 15 €.
That's a restaurant that deserves a second visit, to check a more elaborated dish.

I didn't know if I would post this tip here or in the "To see and do" section.
I never stayed there, but I visited it and find it a marvelous element in the romantic whole of Sintra.
So, take my advise, go there, visit the place, and, if you're free and can afford it (it's so expensive as expected)... stay for the night.
