    All the other reviews are correct as there is no customer service at this location, you do not ever get the right food and when you call the phone rings once and goes straight to background noise like someone answered it and is refusing to talk to you.

    There were two cars in front of me, it took over 20 minutes to get my cold food and then the order wasn't right.

    I've been to this location twice and they screwed up my order three times. Yes, that math is correct.

    Apparently you have gotten new help, yay. Not the fastest yet but so far 100% correct on all orders, hot and fresh and a very pleasant employees.

    (Drive thru) Just ate an early lunch and am disappointed. Got a deluxe chicken meal and a side of nuggets. The problem is I ordered an Arnold Palmer (half sweet tea & lemonade) and they were so focused on my “special request” that they forgot my fries and sauce. And the drink tastes off but I don’t know if they used the last of the tea on me or something.
