Lunch on the cheapWe just skied 3 days at Alta/Snowbird and I spent under $10 for lunch both days at Alta, and about $12 at snowbird. A bowl of Chili runs about $6-7 and ditto for Sandwiches or burgers.
Here's a bit of advice if you want to save a few bucks, go to a convenience store and pick up some small items like a bottle of Gatorade, or cans of soda, yogurt, chips, fruit, cookies etc. You can buy your soup, sandwich or chili at the cafeteria, then pay about 30-50% for the other items you buy at 7/11/.
Also- the cafeteria at the snowbird (tram base) was not very good. You're better off with the pizza place or buying a sandwich at the market.
The ultimate cheap- there were hoardes of young kids eating Ramen noodles for lunch. They sit on benches down by the lockers!
