What to do and where to go in Santiago

Hi again, people from this world and other ones!! Welcome to Santiago of Chile, our great active capital, I've lived here since I have memory, trapped forever! mmm, maybe in the future that won't be so xD
Certainly most people here know many places to visit, however, some foreigners don't. In that case, I want to tell you about some of these places. We have museums, parks, hills, representative buildings, theaters, and so on, but I'm going to suggest you some of them:

-The Museo Chileno de Arte Precolombino is Santiago 's finest museum, with a beautifully presented collection of pre-Hispanic art drawn from the whole South American continent. Highlights include elaborate Meso-American incense burners, Andean textiles dating back as far as 3,000 years, and Maya carvings - not to be missed on any account.
-Try a fresh seafood lunch at the stately Mercado Central, surrounded by stalls packed with glistening sea bass and salmon, and buckets of salt-crusted oysters, mussels and clams.
-Don't miss the changing of the guard at the government palace (the splendid Palacio de la Moneda) when hundreds of green-uniformed soldiers in high black boots "goose-step" around the square to the Chilean national anthem.
-Climbing up the exuberantly landscaped Santa Lucía hill - via a maze of swirling stairways, turrets and fountains - is an essential part of the Santiago experience. Your reward is sweeping views over the city, impressive even when the smog is out in force.
-I can't forget our dear Plaza de Armas. This central plaza features famous monuments, the Governor's palace and is the point from which all distances to other parts of Chile are measured. Moreover, you'll have time to sit and relax on the many benches at all hours of the day. Nice place, there's no doubt.

Anyway, there is a lot of things that foreigners can do in this city, for example: travelling on our well-known subway, Metro of Santiago, which I think is a good and fast transport to get to many areas of the city (don't take the Transantiago, please, when you do that you'll know why I tell it you xD)
Biking traits, eating typical chilean food, going to theaters...I can't describe you so much, my head's spinning haaaa!! If you want to enjoy all these places mentioned or do a lot of things here, you can visit us anytime, it's really worth to live in this city.
