Ishar sweets I have visited more than twice or thrice. Once while returning from Kasauli I stop to have Kulfi and Rasmalai. Kulfi was extraordinary. One is not enough for sure. You want more.
Second time while returning from Solan I stop to taste Gazar ka Halwa (Rs. 40 per plate) and Gulab Jamun – hot and delicious.
Ishar Sweets is situated on National Highway 22 at Jabli approx. 24 km from Kasauli and I guess approx. 10 km from Dharampur. If you are driving towards Shimla from Chandigarh or Pinjore the sweet shop in on right hand side. If you are driving from Kasauli, Dharampur, Solan or Shimla it is on the left hand side. Not only it serves delicious Kulfi but it is also famous for varieties of sweets and namkeen. Pakora, Samosa and Kachori few more added attractions.
You must stop at Ishar Sweets at Jabli.
Chandigarh is 40-45 km away I guess.
