I stumbled on a great article that covers many of the restaurants in Mendoza recommended in this thread. It really sounds like some fine eating.

The Park Hyatt concierge has recommended La Bourgogne, on the grounds of Vistalba Carlos Pulenta. She tells us it is about a 20 minute drive; however, the article I referenced above says it is about 40 minutes. Gaucho100K, what do you think? We'll have a car. How difficult is it to find? It only matters because we will be stepping off a plane at 11:30am, then going out for lunch. Also, is there an online map that shows where this is? I've had no success in my search.
