    Awful. First the girl working the window was rude when handing my food, so then i knew to check it. I had to reorder TWICE, when i get my order it has cheese and the manager or whatever said "its just cheese". I do not care if its cheese if i order something completely plain, something that i reiterated MULTIPLE times, guess what I dont want cheese. Don't ask me to eat something I dont want to eat because you are too lazy to remake the food.

    Avoid this location. They are trying to cheat the corporate ticket times by printing your order and saying it's done before they even touch it. Then your printed paper sits on the screen until they finish all the drive thru and walk up orders. They are trying to reduce their order times and look better for corporate. They don't care about anything but numbers. Then the manager will lie to your face about it.

    Got my coffee order incorrect, as the table across from us. Were pretty good about fixing it when brought to their attention.

    Deplorable. Should have noticed before I went that the management doesn't even care enough to respect the flag they fly. McDonald's flags are not only higher than the ripped up American flag, but new and bright. Absolutely detestable behavior that is absolutely on purpose.
