Singular, Meet Plural

       Carrows Restaurant is the location of my blog post today.  A huge handsome menu titled Classic American Kitchen and with the headline "THEY'RE BACK":

       "You've spoken, and we've listened.  Carrows is proud to bring back all the classic dishes that's made us famous for more than 40 years."

       There are lots of Carrows in California.  How many hundreds of these menus have been printed and are being read this very day?

       How could Carrows have missed an obvious mistake on the front cover of their menu?  "All the classic dishes that's made us famous"?  Plural noun, singular verb?  And even headed "THEY'RE BACK"?

       It's not common to see "that've," but it would be fine.  If squeamish about the contraction, they could just make it "that have."
