You will also find a cafeteria here.

From the left side of the Water Storage Tank and the main gate of the Govt Primary School, Dharamkot a jungle trail starts. After an hour of walk through the Jungle,it will lead you to the Gallu Devi Temple. One can also hire a taxi/cab/auto-rickshaw to reach Gallu Devi Temple. But It'll be costlier due to very poor road condition.
There is an alternate route for the Trek which is a shortcut for Gallu Devi Temple, but a hard and stiff trek and will consume most of your energy, so try to avoid it.
This route starts from Bhagsu Nag area. One can follow a steep trek on the left of German Bakery which goes through shops and a temple and then Bhagsu Nag village and will finally end on the back side of Gallu Devi Temple.
Reaching Gallu Devi Temple, you will come across another cafeteria named Rest A While, and Sun & Moon Café behind Gallu Devi Temple. You can see Kareri and Bahl Village on North-West direction and Bhagsu Nag in East from Gallu Devi Temple. One will also find three Guest Houses, providing rooms for stay for INR 500/- per night (approx).
