It's a pretty big chain so if you've been to one you know what they're all about. I like this one in particular because they have later hours, no annoying kids or families, and is newer on the inside. Bathrooms have keycodes which is a hassle--FYI the code is on your receipt.
Lesser known fact about chick fil a is how awesome their breakast biscuit sandwiches are. Don't get anything with eggs, the eggs are no good (afterall, these people make it pretty well known that they think the chicken came first) but the spicy chicken breakfast sandwich especially with cheese, pickle, and chickfila sauce is what makes life good.
