Where to go and what to do in Santiago?

Well, if a friend of mine would come to visite me from other country, the first place that I'd take her or him is to "Cerro San Cristóbal" because it's a beautiful place, with a lot of nature, it's like an oasis in the middle of the city. If you go there, you also can visit the "Jardín Japonés" and take some pictures, because it has a very oriental environment, it's like to be in Asia. After that, I'd take him (let's suppose that my friend is a boy) to walk around Providencia because that part of the city has so much things to see and places to visit. We can go to "Drugstore" which is like a place with a lot of stores and you can find things like sunglasses and different kinds of clothes. Then we can walk downtown or take a bus and we will arrive to "Plaza Italia", a famous place of Santiago, because people go there to celebrate sport triumphs. After that we can go to "Parque Forestal" and have an ice cream in "Emporio La Rosa" which is a good place to meet friends. After that I'd take him to Barrio Lastarria and we could watch a movie in "El Biógrafo" a very ancient cinema. Santiago has a lot of places to go, an every place can be a good place if you are in a good mood and with someone that you really care.
