Ears were burning, so I thought I'd help clarify. There are different kinds of dosirak, since it translates to "lunch box." The kind I talked about in my blog were part of a food trend at restaurants in and around Seoul where the dosirak was either an appetizer or substituted for rice. Fat Man's dosirak are take out full meals, and I honestly haven't come across those types outside of dunkass (read: Japanese influenced) restaurants. The dosirak "shakers" I was introduced to by Koreans, and the background information on the blog were basically verbatim what they told me. They're just called "dosirak" or "benddo" on menus, but you can tell they're the shake up kind because they're 2,000 won.
