It’s a lively yet unhurried place, where the pace naturally suits those who savor the simple pleasure of a morning or midday meal shared among neighbors and friends.

We visited on Saturday morning around 9:30AM. It was about a 30-minute wait to be seated, which is okay, but their waiting area is very small. Once we were seated, our drink order was taken, and our drinks were brought out right away. We ordered our food, and it was brought out pretty quickly. I ordered the Biscuit and Gravy with eggs and bacon. The biscuit was really good. It was dense but still fluffy. It had a bit of a sweet flavor. The gravy was thinner than a normal gravy. It had a good flavor, but I prefer a thinner gravy. The eggs were cooked well, and with a bit of salt and pepper, they had good flavor. The bacon had good flavor, but it could have been cooked a bit longer. The serving size of the biscuit and gravy was smaller than normal.... but it was just right for me. The (2) pancakes were large and had good texture but were slightly cool. In general, all of the food could have been warmer, but I understand that we were there at a very busy time. The staff were all very friendly and helpful. We would definitely go back, but we would try to get there early, and I would try their Eggs Benedict.

First time dinning here and the food was excellent. Had eggs benedict and the eggs were cooked perfectly and the sauce was hot. It was really busy but the food came out fast. Will definitely return.

Always great food, great service. Regular customers for years now the only time I've been disappointed is when the wait is too long. Which is pretty rare. GENEROUS MIMOSAS!

I have lived in Oakley for years, can’t believe this is the first time here! Doesn’t look much from the outside but the inside looks pretty cool. Looks like an old diner with your normal adds on the wall, old Route 66 placard and a mural painted on one wall. Love the vibe, the smells of good food and the loud sound of the hustle and bustle of the kitchen! The food was amazingly delicious. I think I tried everyone’s food on the table. The chicken and waffles, Buffalo wings, French toast, and Eggs Benedict with sweet potato fries. Those bacon that came with my French toast were nice and crunchy and they were not one of those skinny bacons. The staff were super nice and very attentive. And their nice smiles were an added bonus! They kept the refills going. I didn’t know what to expect about the price but I think it was standard. Oh FYI, their hours of operation is very limited so if you want to come they’re only open until 1pm and it gets crowded. So be prepared to wait a little.

I recently stopped by this classic diner in Antioch, and it was quite the experience. The atmosphere was lively, with a nostalgic vibe that took me back in time. I decided to try their signature burger, and it did not disappoint. The patty was juicy, cooked to perfection, and the toppings were fresh and flavorful. The portion size was generous, leaving me fully satisfied. However, the fries were a bit underwhelming; they lacked the crispiness I usually enjoy. On the bright side, the staff was friendly and attentive, making sure my coffee cup was never empty. One thing to note is that the place can get quite busy during peak hours, so there might be a bit of a wait. But overall, if you're in the mood for some hearty comfort food in a welcoming setting, this spot is worth checking out.
