With big-deal bong brands such as Zong, Kaos, Chalice and Chong, this shop is a smooth smoker's paradise. Double-sided glass means high quality, and can mean high prices, too -- up to $200, but well worth it for a connoisseur. The shop also has less expensive and almost-as-cool water pipes in several media and an informative and friendly staff to show off the pageant of pipery. Of course, this trippy, 12-year-old trove sells more than pipes. Garments with stitched pockets for stashing keys and other "small personals" hang from treetop racks, alongside the usual whacked-out posters, tee shirts, tapestries and plastic-beaded curtains. To complete the mood, choose from an array of rock-star incense, like the Bob Marley Variety Pack or Grateful Dead rose-scented sticks. Don't miss the 11-hose hookah near the register -- an 11th-anniversary gift last year from famed batik artist and pipe designer Jerome Baker. Careful, though: Insinuating the use of illegal substances will get you a swift kick out the front door.
