We were lucky we booked into the Six Peaks early on in our trip because it was subsequently closed for the remainder of our stay. For at least two of our party of 6 it was the best meal we had all holiday - the food was really excellent quality and well worth the price paid. For me, I slightly preferred the atmosphere and food of Plumpjack's in town, but it was a marginal call. The Six Peaks is America's version of fine dining (i.e. excellent food, not massive portions but people still don't seem to dress up for dinner there) and we all enjoyed our time there. If you're staying at the Resort then there's no excuse - one night in this restaurant is a must during your stay (if it's open!).
