Where to go and what to do in Santiago

I think that the first place that I recomend to visit is down town because I think that is an interesting part to know not only of Santiago, is an interesting place in every city, bacause shows you about the people that live there, the culture, and other interesting things that you don't see in other place of the city. After that, I think that i will take to this person to know places like "el parque forestal", "bellavista" and some little streets that are near from there like "viña del mar" that is my favorite. I also recomend go to "cerro san cristobal" in the afternoon, is a beautifull place and have also a beautifull view of the city.
Depends of the preferences of the person I will show him or her different places, because I think that this city has diffrent things, places, and things to do for different tastes, so we have alot of posibilities.
At the night I will definately take him to the Bellavista neighborhood , particulary to "maestra vida", because in reference with my experience is one of the best places to go to dance, always has good music, latin music, and sometimes play good groups of music.
