Thanks for posting this. Portland + Seattle also have underground restaurants (which got so trendy they bore a legit manifestation, "Family Supper" ah, Portland...)
I did some research about this since yesterday and found mostly information for selling food you make in your house, but sell outside your house. They call it "cottage food," (i knew the expression, but not what i meant legally). I found out that "cottage food acts" are enacted state by state, and that Oregon (where I live) has a permissive one.
As for serving food right in your house, i haven't found much info yet.
