Retired Cook here, can confirm. Local is best. I only worked for locals when I did it, Chains bring in a lot of stuff frozen and such that contain stabilizers and such: case in point, alfredo "white" sauce. The real thing can only be made to order, there is literally no substitute without watering it down and adding gum emulsifiers to preserve texture...I will eat at home over a chain, I order food once every month or 2, local restarants, Thai, chinese, pho or bbq. I eat there when I'm craving food I cant duplicate.
