Sources for shirataki noodles?

What are good places, particularly within the city, to buy shirataki noodles?

Shiritaki noodles can often be found at the Broadway Supermarket, in the strip mall just north of Lawrence, on Broadway.

They are always available at Chicago Food Corp., on North Kimball, and at the Korean grocery store next to Kang Nam, on N. Kedzie.
