"I recently had the pleasure of discovering Mustard Cafe & Grill in Foothill Ranch, and what a delightful little gem it is! From the moment I stepped in, the atmosphere was incredibly inviting—peaceful and soothing, making for a truly relaxing dining experience. The service was outstanding; our server, Maria, was simply wonderful. Her genuine smile and professional yet kind demeanor truly lit up the place, ensuring we felt well cared for throughout our visit. Everything came out perfectly, and it’s clear the staff takes immense pride in their work. I opted for a custom three-egg omelet filled with spinach, tomato, avocado, and Swiss cheese, served alongside perfectly cooked potatoes and delicious sourdough toast. It was absolutely fantastic, clearly prepared with care. I also tried their avocado toast, which was a definite highlight, and the coffee was excellent—a perfect complement to the meal. It’s easy to see why this spot is highly recommended. With plenty of parking available, a fantastic menu offering great breakfast and lunch choices, and an owner with a wonderfully positive attitude, Mustard Cafe & Grill is now firmly on my list of favorite places. I initially came for breakfast but am already planning my return for lunch. This cafe truly excels in every aspect – food, service, and ambiance."

"I love finding places that aren’t big chains, and even though I learned later there are a couple of other locations, this one still feels like a cozy. It’s small, inviting, and has its own personality—plus theres the option for outdoor seating. I stopped in for brunch and tried the Shakshuka for the first time… and wow. I went out on a limb but every bite was amazing. The food here may look casual at first glance, but the flavors are not. My server was so friendly, helpful and attentive. While I was there, I noticed so many regulars coming in—some just picking up to-go orders—and and with the conversations I overheard you could tell they are definitely often visit. supports this place. I already know I’ll be back and yes, I’ll be ordering that same dish."

"Stopped in on a lark after arriving at Orange County Airport and having some time to kill. Great vibes, eclectic music 🎶 in the background, really kind and engaging service and a breakfast bowl that delivered a tasty vegetable and protein packed punch. Locals and regulars greeted warmly by the staff and us non-locals soon made to feel like we belonged as well. Hung out over coffee and played a board game with my wife —not rushed out. Really good experience."

"Such a beautiful and soothing place. I was really not expecting that it would be so calm and such a nice ambience. I got my food to go because I’m not from here and was in a hurry to get home but I would come here on my days off if I could. Food is delicious and is very nutritious honestly I wish this place was closer to me so I can become a regular customer.i had the breakfast scrambler."

"Great food and experience. quick service restaurant. I came in with my little ones and the cashier helped serve us water cups (they are self serve) and brought us a high chair. The food was delicious and they had so many options. We had the pesto panini with berry salad and chicken tortilla soup."
