I've been a patron of Cloud 9 for 5 years now, and I can safely say it is the best hookah lounge in Vegas. I've been to many other lounges, both here in Vegas and elsewhere, but none of them make you feel as comfortable and chill as Cloud. If you're looking for a fun party vibe, definitely go on a Friday or Saturday night. They always have awesome live DJs and plenty of room to dance. On the week days it is much more calm and a nice place to relax with friends. The staff is always friendly and attentive and makes you feel almost like family. If you are new to hookah or don't know what to order, they are very knowledgeable and can suggest great options for you. A big plus for me is that it is always clean and is big enough that you don't get that claustrophobic feeling some hookah places can give you. It's also easy to find and has plenty of parking. If you're looking for a great hookah experience, I would definitely give this place a try!
