Flying to Santiago Chile-need to know what to "must see" in the city of Santiago in one or two days?

I am going for business to Santiago, and I may only have 1 day to tour the city. Please if you can give any suggestions of what places I cannot miss to visit, or are worth visiting. As well as suggestions on places to shop for typical souvenirs.

Thank you all!

Hi
I'm chilean and I think that you should visit the Santiago downtown (Santiago Centro) where you can find nice old buildings and amazing works of art.

you also should visit Palacio La Moneda which is the biulding where the President works

If you have enough money you could go to the following "comunas": Providencia, Las Condes, Vitacura. where you'll be able to find nice souvenirs and other expensive gifts. in these "comunas" you can find a lot of shopping malls with very exclusive stores. :D

but if you like pieces of craft Santiago is full of places called "ferias" where you can find these things. you cand find one near the Santa Luc铆a hill (that you should visit it, btw.)

I hope you enjoy Santiago and if you need a interpreter or a tour guide, here I am. jiji

take care, bye.
