You can visit this restaurant after seeing Namgyal Institute of Tibetology. But The Easterner is not highly estimated by Google users who assigned it a below average rating.
Great experience! Very nice ambience with well trained staff & brilliant food, music, environment. Manager/owner helped us with a special request as well!! Kudos!
When in Gangtok, Sikkim do not forget to check this place out. In town centre, live music, buffet, seat with a view, good cocktails, friendly staff, tasty local food, free WiFi, it has everything a tourist looks for.
