I second what Fraser says re Weisshorn and Chez Gaby.
Nellys Bar is a good place for a drink and a springbok steak. I'm still not sure if the place ever closes.
Avoid Grampis - it's a tourist trap and the service isn't great.
There's a fairly standard Molinos branch too.
For apre ski check out Papperla bar. You'll hear it before you see it
