Need Santiago (Chile) recommendations

i may be able to add 3 days to a biz trip to Santiago Chile. Would love some recommendations as to what to see/do.
Of particular interest are wine tours which combine food and wine tasting, and with those tours I like quality over quantity. (Prefer 1 or 2 great experiences over 6 or 7 nice ones) if you can recommend specific tour operators, that’d be wonderful.
Also, beyond wine and food, what should I not miss?
