Go here for cocktails and sit at the bar if you can. Ask for the full cocktail menu, it’s extensive and creative. My favorites are the Beef and Bee or the King Over Waters.
As far as food goes the best thing is the burger (aspen locals will notice they’ve raised the price). I was really disappointed to see they are now serving verlasso farmed salmon from Chile instead of wild Alaskan salmon. They do have Alaskan halibut however.
