Tei-An at One Arts Plaza in Dallas: The Buttstory

From the ever-curious mind of SideDish reporter, Andrew Chalk:

Recent reports and videos on the making of soba noodles omitted the most curious fixture at Tei-An. No, not the rooftop patio (at least, as yet), the doors to the bathroom stalls. You step into a cubicle that appears to have a glass panel in the door. So much for privacy! However, when you close the door, the glass panel turns opaque–at least, from the inside. I assumed (hoped) the effect was two way, and (thankfully) no crowd gathered outside. This is a talk-inspiring design feature for a restaurant

I first heard of this type of glass being used in the changing rooms at high-end clothing stores. Apparently, it is made with a Piezoelectric crystal formed on the sheet. I wonder what happens when the electricity fails?

  1. I wonder what happens when the electricity fails?

    The doors are normally opaque, and turn clear when electricity is applied, so if the power goes out, they stay opaque.

    Thats the first thing everybody asks about that kind of glass…

  2. yes the bathrooms are cool at that restaurant. i think i first saw this type of door on a Real World series recently.

    anyways, too bad the food at tei-an is really not that good. the setting is very lovely though..

  3. Sorry, can’t leave this one unchallenged:

    anyways, too bad the food at tei-an is really not that good.

    You sir are mistaken. Sushi is always clean and fresh. Menu is seasonal and creative. And where else in Texas are you going to find a chef who has spent so long perfecting his soba making craft?

  4. What a great excuse to go back to one of the best restaurants in Dallas and investigate.

    Until such empiricism I’ll offer some speculation.

    Though I hate to disagree with something as authoritative as Yahoo Answers, I suspect the door is a liquid crystal or electrochromic based device.

    John Evers is probably right (entropy, liquid crystals, and so on) but i will add (gratuitously) that if the electricity fails the bathroom would be mostly dark and privacy would come from a different effect entirely.

    i think i am responding to this mainly to cite the following link, which never fails to crack me up.
