Here’s word of an enforcement action from our friends in public health in Seattle:

Pho Hoa Bihn Vietnamese Noodle located at 4732 Rainier Ave S, Seattle
was closed by a Public Health food inspector on Nov. 28, 2008 at 4:20
pm due to a sewage backup in the establishment which is an imminent
health hazard.  The establishment will be reopened once the inspector
confirms that the issue has been resolved.
