Hookah lounges provide an atmosphere where friends gather and smoke detectors go to stir up trouble. Partake in flavored puffs with today's Groupon: for $20, you get $40 worth of hookahs, snacks, and nonalcoholic drinks at Sitara Hookah Lounge.

Located on the Strip, Sitara Hookah Lounge packs fine puffing products into the age-old, long-hosed smoking vessel. Lean back in ultra-chic padded booths and spell your postman's name in the smoke with a Fumari or special Sitara blend tobacco ($15, $7 refill). Starbuzz and Al Fakher tobacco ($12, $6 refill) burn with pleasant flavored aromas as the hypnotizing sounds of the bubbling water base evoke ancient caves and modern percolators. Keep your mouth busy while waiting your turn at the hookah with Boba-brand drinks ($5) or sandwiches and assorted finger foods ($5+). Sit cross-legged like a sage within the quiet contemplative weekday atmosphere, or tap feet to the sound of music during more rambunctious weekends, when the lounge swells with people and single smoke rings searching for consonants to give their lives meaning.
