“My family went hiking this weekend with our dog and decided to try this place since they had outdoor seating. Sunday Diner had fantastic food, and even better service! I definitely recommend this place to anyone visiting Clayton!”

“I will be back to this place! Found it while traveling to Tennessee and there is not one bad thing I can say about this place. We got extra sides and deserts so we could try as much as possible and everything was perfect!! And for the guys, yes the ribs are good! Make sure you get the corn nuggets too!!
The food was delicious. Good southern style lunches and breakfast. Today was Country Fried streak and vegetables with peach cobbler for dessert. The service was quick and friendly..”

“I LOVE to share about places like this! A little off the main road, small diner with super friendly service, plenty of coffee refills. Let me tell you about the pancakes….when they say “dinner plate’s size, they mean it! They were HUGE but oh so delicious! The breakfast potatoes were amazing. You really should try this place out.”

“New to the area and had family visiting. We all wanted to try a local place, but had no idea where to go. So glad we chose the Sunday Diner! Food was YUMMY, with huge portions, and service was exceptional. We had eight in our group and everyone loved the food. Family members can’t wait to go there again when they come to visit.”

“You literally could not ask for or find a better place to have breakfast. I’m a little snobby about pancakes because they’re a very simple food that takes something special to make memorable. Their pancakes are more than memorable. They are my new standard for pancakes at a restaurant. They are almost bigger than the plates they serve them on, and they are so fluffy and thick. If you order the bluberry ones, turn the pancake over. The sheer amount of blueberries will shock you.
Their prices are exceptionally low considering the quality being as high as it is. Everything they prepare taste fresh, and their ingredients seem premium. You will notice this especially with their potatoes and blueberries in their pancakes.
I will probably never go anywhere else in Clayton for breakfast. It’s that good.”

“Always a pleasure to visit Sunday Diner. The service is prompt and friendly; the food is tasty and homey, and you get plenty. The desserts look good, though so far, because of being full when dessert time comes, I haven’t tried them yet.”
