Did the ski bum thing in SV for 3 winters over 20 years ago, still go back from time to time. Love the place for the skiing, food and people. Best breakfast, hands down is the Kneadery.
Quick lunch try amazing sandwiches at Johnny G’s sub shack or KB’s (Ketchum Burrito). Classics after skiing are Apples or Grumpys, even both base lodges can be fun. Drinks at Sawtooth Club, Olympic Bar at Michel’s Christiana, Duchin Lounge and SV Wine Company. Nice dinners try Pioneer Saloon, Sushi on Second, Michel’s Christianas, Ketchum Grill, Knob Hill. Party till the doors close at 2am ish at the Casino or Whiskey’s. Check online for pricing to fit your budget the places I mentioned vary from cheap (relatively speaking) to expensive.
