This diner is decorated to the nines for every holiday. Went here this past Sunday, and it’s fall themed now with Halloween and a little of Thanksgiving. It was beautiful. Went here last year during Christmas time and it was even better if you could believe that. Good was okay, diner food. We had breakfast. I was taken back at the upcharge it is to add cheese to an omelette. I ordered the artichoke hearts omelette which on this September 2025 Sunday it was $14, and to add cheddar cheese into the omelette it was $18 total!! $4 for cheese is a little absurd if you ask me. $4 for adding bacon into the omelette would’ve been fine, but I didn’t ask for that so I didn’t receive that, but I couldn’t imagine what the upcharge for that is! Omelette came with home fries and toast. I got wheat. Comes

I had never heard of this restaurant and when I stepped inside my mind was blown! Wow ! Loved how they made the venue different in a good day. Amazing ! The waitress was perfectly attentive and obliging. Nothing was too much trouble. Coleslaw and pickle was delivered for all of us and the meals were huge. Felt catered for, we left full and happy. Well done ! We found a gem there ❤️

★★☆☆☆ 2.0 Desiree Agudo · Jul 2025

Went there for Thanksgiving 2025 and it was even more disappointing than last year—definitely not worth the exuberant prefixed price that turned into $80 for one. Ordered the Lamb which didn’t taste like lamb at all. The white cream of Turkey soup, had no taste. But the Greek salad was generously sprinkled with Feta Cheese so it definitely escalated the taste. The sweet potato was by far the best part of the dinner. It was so delicious, I ordered two to go. The baked clams, basically non existent and the Asparagus, not grilled or sautéed or anything. The disappointment was so overwhelming, forgot to ask for the dessert which was included with the dinner. The place was extremely crowded and had to be seated at the counter. That I have to say, was very comfortable—and no, I’m not being sarc

★★★☆☆ 3.0 Laura D · Dec 2025

The oconee is a an average diner. It's not bad but it's not phenomenal either. The atmosphere was nice, it was very decorated for the holidays which was great. Everything was clean too. The service was great, our waiter was phenomenal, he was very kind and knowledgeable of the menu. The food was average. It was basically what you can expect from a classic diner. It wasn't bad at all, just average. I got the grill wrap, it was a little bland but still good. The prices were just a smidge high for a diner but nothing too bad. I did really appreciate the free cookie after dinner, especially since you don't find many places that do things like that anymore. All the desserts I saw in cases also looked good. Overall if I was in the area and needed to eat I would go here again.

★☆☆☆☆ 1.0 Lisa Sausa · Mar 2026

We have been going to Oconee for as long as I can remember. Today we were very disappointed. My fiance ordered a cheese burger deluxe. It was like a hockey puck, 1 slice of fake American cheese. I ordered a triple decker chicken salad. It was so dry and the bread was as thin as a saltine. The waiter had an attitude. I can understand the chef being off but to be honest they have been going downhill the last year or so. Don't know if anyone else has had issues. Wish I had taken pictures.
