In Whistler Village by the IGA grocery store: 

Opa! has fabulous Greek gyros and more.  This was a favorite place.  Big portions.  There is also a Chinese takeout place attached.

McDonald's is decorated very nicely.

KFC - not a favorite, but if you like it, it's there.

Behind the IGA are Quiznos (subs) and Domino's Pizza.

At Blackcomb base in the Fairmont Whistler Hotel is Portobello which has a $4.75 coffee and pastry combo for breakfast.
