UBC hostel is you best bet if you book early! Chill place, usually find some cool people to chill/ski with. its the cheapest place in Whis at around $20 a night. If you want to eat out go to El Furns as the guy said before me.
Do not buy food for lunch/ breakfast near the village, you wil pay about 10 dollars for something that isnt that great. A burg combo on the mountain is like $18 or something ridic. If you get the munchies or need a quick snack, there is a place called Moguls Coffeehouse next to the grocery store in the village. It does thse huge cookies that are like 20cm wide by 2cm thk. Best value for money i have seen in Whis.
hope this helps.
