After the hike, you have to keep walking, google maps will not work here, just talk to the locals in the village and one of the last buildings in the village of Kalga is where Holy Cow Cafe is located.
Please keep in mind that there are not many people you will find in this village but it is not impossible. There are pretty good home-stays if you keep walking inside the village. As soon as you finish the hike and reach the top, there will be a small restaurant, you can enquire there and start walking further inside the village.
QUICK TIP - Please carry enough water and wear proper shoes
It is a bit difficult to find this cafe and it is usually not crowded. The food at this cafe is just very yum and at a very reasonable price. Do no forget to order pizza here.
