OK

The OK Diner on the A1 near Grantham. The restaurants have a retro, 1950s-style, American diner theme with popular 50s music, plenty of chrome details and 50s memorabilia on the walls. There are three dinners on the A1 and in our experience all provide a friendly service and plenty of food at a reasonable price. Word of warning if you plan to stop - they do get busy.
