Breakfast Menu "Del Taco" Walnut

Manager Claudia is here day and night, dedicated worker, del taco is so lucky to have such an amazing manager ! Keep it up Claudia we keep coming for your great customer service!!!

A good clean location with well trained staff. The food was prepared fresh and prompt, served professionally and courteously by the workers. Parking at this location is ample, with a small lot designated for Del Taco, and an additional lot for the nearby shopping plaza. I would recommend this location based on it's convenience and consistent quality.

Awesome people. I paid for the food for guy behind me it wasn’t much but the smiles on the girl at drive through and the person I paid for were price less. Let’s do these acts of kindness when ever you can to create harmonious environment for over next generation. 😊👍

This place has been my childhood growing up. I would often come here after both middle and high school to hang out and eat cheap tacos, especially Taco Tuesday. It's great fast food, and the food always comes out quickly. Great for its price, especially when deals are present.

On my way home I thought I would swing by DelTaco for some fries and a drink. It took forever to get my fries, I thought they would be fresh. When I was back on the road and dipped into the bag they were not hot at all. They tasted like they had been sitting under the heat lamp for a very long time. Not going back to this Del Taco.

Just went through the Drive Thru. Washed my hands and unpacked all the food onto my own dishes and washed my hands again. The food was absolutely delicious! THANK YOU DEL TACO!! Thank you to your employees. You all stay safe too!! ❤️

Very sorry that I had to post a negative review but I am doing so specifically due to the way the manager handled an issue with serving stale fish tacos at 11:00 pm. After several of my latest visits being poor quality of food, I had to return this particular night because there are not many choices for places to get a late night meal in Diamond Bar. After this chance, I personally will not go to this Dell Taco anymore due to the fear of what else the food preparers would carelessly do. Be very cautious and check your food before biting into it. The Night Manager will lie to you and say " nothing is wrong, your food was freshly made." The fish that was inside of the taco was hard like it was nuked in a microwave and dripping with saturated oil. It was clearly old and should have been disposed of, but they chose to reheat it and serve it. Good luck with eating here...

I actually received friendly service which rarely happens at this location when I visit... the food is prepared very sloppily, as the ingredients aren't usually in the tortilla. Very frustrating when you pay extra. Management does not care if you enjoy your meal or not.
