They make the best sandwiches and fries in town! We stopped by on a Thursday morning and ordered the Copperlocks Fries before hitting the road, hands down, the best decision we made. The owner and staffs are very kind and welcoming. On our first visit, it felt like stepping back into the '60s, when everyone greeted each other with genuine smiles. Highly recommend this spot — don’t miss out if you’re in the area!

Great selection of traditional American Diner fare such as shakes, burgers, pastrami, Monte Cristo sandwiches, etc. Breakfast is served all day. Our party ordered the bacon cheeseburger, pastrami sandwich, chicken sandwich, Monte Cristo sandwich, and gyro. All items were satisfactory. The pastrami and Monte Crsto breads were grilled nicely. The servings were average-size. The food took a while to come out. We were informed that this is because everything is made-to-order. The service is friendly and attentive. Ranch costs 50 cents extra. I started adding this into my reviews because ranch is a condiment. I've never been charged for ketchup, mustard, hot sauce, or pickles. I understand charging for extra, but a dish should include one serving of ranch, at least.

We live in Riverside, but when when we're in the Corona area and need lunch, Copperlocks is our first choice. The manager, Donna, is the sweetest lady ever and has treated us as friends every time we've been in. She always has time to chat and share a laugh, something so rare these days. The food is amazing: delicious crisp fries and a giant burger that's seasoned perfectly. And the prices are good, another thing that is rare. We are so thankful for really good food that doesn't require breaking the bank to get! The atmosphere is really nice, well-lit, clean, and homey. We always enjoy Copperlocks and hope to go there many more times in the future! They need to open one on Riverside!

First time trying, I got the Cali burger, it was great! Just needed cheese. My boyfriend got the Monte Cristo and he loved it. Second time, we had to try their chicken charbroiled and the crispy chicken. The crispy chicken was flavorful and juicy. Their fries are good! Service was fast and friendly. Highly recommend

Cute and cozy place for great food. The chicken salad was amazing and they did not skimp on the protein. The restaurant is clean and the staff is very hospitable. Can’t wait to return.
