I am a westernized Indian and can guarantee that this Bhang Shop will give you a good run for your money. The lassis with or without bhang are awesome!
Dr Bhang will also give you local advice that other shop owners will not, hes not there to try rip you off or make a lot of money, he really cares about your stay.
This place is more than a shop, its also a meeting place for like minded people. When i came here i met people from all around the world. From Italy to Canada. It was a lot of fun.
Now the bhang, he has lassis,cookies and just plain mary jane.
This is great stuff and very cheap by any standard! Dont come to Jaisalmer without visiting this shop :)
