I was reading an article in the Denver Post and I ran across the term "beater restaurant." I didn't know what it meant, and I wasn't able to find the term via a Google search. The article is in the newspaper's cold case section, talking about a murder that took place in 1947, so possibly it is an older colloquialism.
From the article, "Founder of Denver school murdered with sister", K. Mitchell, 23 February 2013:
To help in the discovery of Lundy, authorities said he “likes good steaks” that he eats at beater restaurants and stays in good hotels. “He dresses fastidiously.”
The article is rife with inaccuracies and poor grammar/spelling/editing, so it is equally possible that it is some form of misprint. Any insight would be appreciated.
