What town? The nearest town is Pitcher Creek which does has a few guest houses but no real life. The resort has a hostel which is fine; it has dorm and private rooms and is cheap at CA$25/night www.castlemountainskilodge.com .
There's a day centre offering great breakfasts and lunches, and there's the T-bar pub offering beer and pizza. It's a well laidback place, just like the whole resort.
EatingAgain the T-bar or the hostel are your only option.
NightlifeMake your own, or drink it up in the only bar the T-Bar.
