First time there and a bit hard to find. My route was subway line 1 get off station Dongdaemun then exit 3, walk to first alley on left. If lost after exit station, ask a local. Many understand English and just say "Everest".
Don't let the suroundings throw you off. It is not a five star area but the restaurant is a gem. Keep pressing on to the restaurant.
Decor is very local Hymalayan and not too posh but comfortable. Owner and staff very friendly. Take a booth for privacy. All your food comes at once so ordering can be challenging first time. Never mind, it is all good. Very large menu. Try to go with someone who knows what to order. I never do in Indian type restaurants. If in doubt, just ask the server. They will bring you good stuff.
Prices are reasonable. Go early for seating.
