If you are not sure of the manufacturer of the diner, for example, leave that line blank. You must, however, supply the name of the diner, the city in which it located, and the state, or your submission will not be processed. If you prefer not to rate the diner, you are not required to do so. Owners and employees may write reviews of their own diners, but are asked to only supply objective information, and not enter ratings. When rating food quality, keep in mind that most diners serve simple fare.

The historical value of a diner is for many the most compelling reason to make a special trip to eat there. Many classic diners have been severely marred by alterations. With this in mind, you may rate the current condition of the diner.
