You can smoke hookah at the following places in Dehradun:-
- Macoozy lounge at Rajpur Road
- Vibezz lounge at Rajpur Road
- Sheesha lounge and Restaurant at Street number 2A, Rajendra Nagar
There a few more hookah lounges but can’t remeber their names right now. I will add them later.
P.S.- It would be better if you are above 18 years as there have been instances of police raids at these places and they specifically pull out teenagers as it is illegal for them to smoke.
