Dr. Bhang's bhang lassi is one of the smoothest and best I've ever had. Upon one hour after consumption, the camel ride felt like a magic carpet ride and me being lifted halfway in Mid Air.
Make sure you get the correct shop- the name of the shop is now changed to "Lassi Shop" due to political reasons. There's a phony "Bhang Shop" in Fort Parking; approximately 300m from the real one. To make sure you're on the right one, go in and ask for the manager- "Dr. Bhang". Then, ask for the written reviews others have left down.
