The selling point is that if you book a table you get into the castle an hour or so before free gratis. We had plenty of time to wander around, climb the ramparts and enjoy the view of Lisbon by night, so that is a good selling point.
The restaurtant itself is in a beautiful vaulted room. We had no complaints on the service, and I would rate the food as good if very expensive.
However my complaint would be the loos - for such an expensive place I expected something really nice. In fact the loos are probably the worst I came across in Portugal. Shabby, bits of plumbing falling off, and needing a complete overhaul.
