Santabrasa is a long time favorite for me and my wife. I've been there on several different occasions and the experience was always great. Have tried different cuts and lots of different wine options. Sometimes it's pricey, but recommend them all. Acaramelado de manzana is a must try for dessert. :) 4-star rating only because of details below.
* this review is for Santabrasa in Parque Arauco. I've recently been to SB in Costanera Center and all I've felt was that I was having a "fast food at the mall" experience. unimpressive service and food.
