Note: for the next installment of the Our Declining Language series, the Curmudgeon plans to compile a collection of misspellings found on restaurant menus. And I'm welcoming reader contributions. If you spot an error in your travels, please forward the damning photographic evidence via the link at the bottom of this site's main page.
