We stayed in Luz for a week in october with another couple and went to 7 different restaurants.We independently at the end of the week scored out of 10 all the restaurants we visited and this came last, although it has to be said we went to some very nice resaurants, including Artistas in Lagos, and Ancora in Burgau (these 2 are fantastic, I have reviewed them!).
Lovely starters, including prawns in parma ham and asparagus.
My lasagna was nice, although any Italian restaurant not serving a good lasagna would have a major problem, but the chicken and veg pasta dish my wife had was disappointing.
Service a bit slow, and overall it was ok, but we wouldn't rush back.
