Advice wanted: Megève/Combloux

Hi guys - am going to Megève/Combloux over Xmas, would love any thoughts, advice, tips, etc. on

  1. wine (obviously) - restaurant BYOs (yes or no?), good wine shops, any local specialties to try (I suppose Arbois or Swiss is the closest?)

  2. restaurants - local gems or famous spots? In particular, does someone have an opinion on Restaurant ‘1920’ du Chalet du Mont d’Arbois - they are asking eur 240 for a meal but its 3-starred…

  3. ski/snowboard - good rental shop, instructors, runs? Have a car and can drive to nearby resorts.

  4. other activities - someone suggested getting a plane/chopper ride over the mountains? apres-ski activities, bars?

Thanks much in advance!!
Sam
