Look at pictures a-c. Your English-speaking friend is visiting you. Your

I would like to take my English-speaking friend to a restaurant, picture B.

My friend likes such quiet places. I think it is a perfect place to go out for dinner.  A restaurant "A" looks too formal I don't think it is appropriate. A cafe in the picture "C" seems to be a loud place to spend with a friend and the family. So that is why I choose the restaurant "B". Hope my friend will not be disappointed.
