I have been to Haveli twice, the place looks nice, its well decorated and well maintained.
Have tried Makke di roti, Sarso da Saag and lassi with my friends.Food quality is good but quantity was less for the money spent.
It is a well known place in Jalandhar and many celebrities and singers visit it.
I wont reccomend visiting it during summers as its very hot and even ACs cannot provide enough relief, Its reachable by Road.
Adjacent to Haveli, there is Rangla Punjab which is also a nice place.
