Gangtok in sikkim is also the capital of sikkim and a beautiful place. The reason behind is that this is a hilly area, you can easily see the Himalaya mountain range there. Also the greenery of this place is also awesome. I stay in Gangtok for two days only, and experience a new adventure there. Our group done including me various adventurous things like hill climbing, picnic on a hill etc. The hotels in Gangtok are good and affordable. Number of hotels there are not large compare to other big cities. Other places like Tsomgo Lake , Himalayan Zoological Park , Cholamu Lake , Banjhakri Falls etc. were also there and very nice. In short, that was a nice experience in gangtok.
