Courtesy Diner

Courtesy Diner has the look and feel of a classic diner complete with vinyl seats and checkerboard tiles. Diners can opt for a table or go for counter service to get the full effect. Read more

Not sure if it's good sober, but the hangover (2 eggs , hash browns , and chicken fried steak covered in white sausage gravy ) is delicious and only $6.25. They only accept cash.

Whether it's scrambled eggs , pancakes or a "Devil's Delight," you'll never be blown away by the food -- simple dishes that provide enough sustenance to get your though the night. http://bit.ly/1b7jYgN

Good, cheap diner with classic vinyl decor.Both the Hangover and the Hoosier are good options if you like gravy , but they are only available for limited hours.Remember to bring cash!

Tall stack was good fluffy rib-sticking! Steak & eggs - order it rare. Hash browns were nice crispy fresh. Not expensive - we dropped $40 on this including tip. Great staff .

Courtesy Diner has been slinging its famous slingers since 1935. There’s also the requisite diner lineup of burgers , patty melts and more, but make sure you bring cash. By Gabe Hartwig Read more

The service is horrible and when I walked in they never welcomed me. The inside was very disgusting and looks like they never even clean the place.
