Deer Valley was our favorite until we visited Sun Valley couple seasons back.
DV is heads and shoulder above most everyone else. One of the places we usually look forward to skiing (and eating). Food is really good and the skiing is way under rated. The Daly chutes are pretty decent - more fun than Jupiter and Ninety-Nine 90.
Since I now live about an hour from DV, and after having mountain biked there this summer so I could see the layout, I am jonesing to ski there. Because I AM that skier who still loves smooth groomers because I'm finally actually quite good at skiing them! (Working on the off-piste stuff more and more, because hey, I'm in UT now and it's a whole different type of snow here than the Sierras!)
Sun Valley is part of my Snowbasin premier pass. Not sure if we'll be able to take advantage this winter or not. Definitely want to. The older I get, the more I truly enjoy and don't mind the extra bit of cost of a tasty on-hill meal.
I would expect that Powder Mountain's food offerings will continue to improve now that they're going away from their origins. Last season, I was quite impressed with the quality and selection there. Is it weird that I enjoy quality food in a grungy, classic old-school ski lodge environment?
