We don’t believe in huffing it to Sonic or Taco Bell for “convenient” eating, which is why we head to Clovis Highway. Jim Dandy is old-school authentic: local teenagers crowd the joint at noon; the greasy hamburgers are the kind that make napkins and manners a must; JD knows the only respectable Texas way to serve up fries is with creamy white gravy; and dessert choices include a frozen chocolate-covered banana. Cash only.
