This sentence is from a famous British film(Downton Abbey). There is a guy whose face was completely hurt in the war and being treated in a hospital. Almost all of the face is wrapped in bandages, and barely any part (only the eyes may be) can be seen.
And this guy with the unrecognizable face claims that he is Patrick, the heir of the family that runs that hospital. So the family gets shocked -because they have been looking for him and have never seen since his childhood years ago- and do not want to believe him.
So they discuss how can they make sure that this guy is really the Patrick. Some of them says "he may be Patrick, and some others say he must be a liar after the money. So they can't decide. During these discussions, one lady asks the people there?
"Is he like Patrick to look at?"
This structure sounded very different to me. What kind of structure is it? If I got it correctly, I think she means "Does he look like Patrick, when you look at his face?" or may be she means "Does he look at you like Patrick did -when he was a child?"
Can we use this structure for similar situations, when you cant make sure if a voice on the radio is of someone whom you can make sure? Eg "Is she like Madonna to listen to?"
