We eat here quite often because it is close to our home and they offer several dishes that do not contain milk products. They even list out every single item online with the most common food allergies such as gluten, eggs, milk, nuts etc. which is the main reason I go back.
I prefer to go to the CPK on Scottsdale/Shea and here is why: I have ordered the Carmelized Peach Salad via take out and they forgot the peaches. Called up the manager who apologized and said he would refund me, well he never did. On 2 occasions I have felt a little sick after eating the Carnitos Tacos. The location on Shea makes them taste unbelievable but this location is slacking. I've been back to order salads, but after you see slimy-past it's expiration date-lettuce, it becomes quite a turn off.
All in all, we really do like the food, but I definitely think it's hit or miss with the quality control.
