Avalanche was recommended to me by my ski instructor. He was spot on. Both times I went for lunch I had to wait about 10-15 minutes for a table. Your whole party has to be there otherwise they won't seat you.
The first time I ordered the potstickers and sweet potato waffle fries. The fried potstickers were okay, but the sweet potato waffle fries were awesome. You could taste the truffle oil and the creamy dipping sauce was a nice touch. Prices were reasonable and service was quick. The second day I ordered chili and sat in the back by the fire pit.
I recommend Avalanche over other restaurants by the base.
