"We smoke, f*ck off" is spray painted above the bar at Petra Café and Hookah Lounge on South Grand. With that kind of attitude, it's readily apparent that Petra is not your traditional hookah joint. Petra has a variety of hookah flavors, including rose, honey, vanilla latte and several house blends. The prices are very reasonable: $10 for a small hookah, $13 for a large. They have a small menu of inexpensive Middle Eastern dishes ($5 for a chicken pita and a mound of hummus) that they serve up to an hour before close, and sometimes even later. Something that's totally unique to Petra: They give you a cup of bubbles and the top half of a cut-off plastic water bottle. Customers dip the open end of the bottle into the bubbles, drag off the hookah and blow the smoke into the bottle top, creating baseball-sized bubbles filled with perfumed smoke that waft above the crowd like crystal balls uninhibited by gravity.
