I have to give a shout-out to Chipotle. I've been wrestling with a serious auto-immune disorder that causes massive inflammation in my body. Changing my diet significantly has allowed me to avoid serious medication. Chipotle is one of the few places (fast-food or otherwise) that uses quality-enough ingredients such that I can eat it without any inflammation. My only complaint is that they do not seem to treat their employees very well leading to frequent turn-over. If they treated their employees as well as other companies such as In-N-Out I think it would make a huge different.
