According to the press release from Magical Elves, the production company behind Top Chef, Seattle's open casting call for Season 6 contestants will be held next week:
Wednesday, February 11
10:00 a.m. - 2:00 p.m.
Canlis Restaurant, 2576 Aurora Ave. N., 283-3313
requests you to mail in an application form, a photo, and a video, the
press release for the in-person interviews only says you should show
up. No word on whether you'll be required to do a screen test, win a
QuickFire challenge, or survive judgment by Anthony Bourdain. Perhaps
you should bring along a satchel of gels and spices just in case.
UPDATE: Donna Lee at Magical Elves says that people who come to the casting call should bring the application, photo, and video described in the above link.
