Let's see what 724 Hookah is all about. According to their Facebook page, they have really good hookah prices ($12) during happy hour. I've never been there, but it has very good Yelp reviews and looks worth checking out. If anyone is interested, we can grab drinks or food at a nearby spot afterwards!
724 Hookah is located on Geary Street near Leavenworth in the TenderNob neighborhood of San Francisco.
