We found Drfit from Yelp and decided to check it out after a movie. The great reviews don't even do justice to how awesome this place is. Ali, the owner, is not only incredibly welcoming but he is very friendly as well. The shisha was great. Ali has a ton of flavors to choose from including some rarer finds. He uses Coco Nara coals and KM pipes. The pipes were clean and the water was fresh. Each shisha flavor has its on hose so you don't worry about mixing flavors.
We were visiting from out of town and will definitely come back any time we are in Pittsburgh. All's hookah could hang with the best hookah bars in Queens.
Give it a try!
