    Where do I even begin..... This location has subpar service at best. The morning crew lacks customer service awareness and seems to have zero training on how to make coffees that are on the menu. One would assume there is a procedure in place to make these coffees consistently, but there is zero consistency. They are usually extremely bitter, or in this instance, my iced caramel machiato was just cream and caramel, zero espresso/coffee. Or for example, I have ordered countless iced caramel coffees with extra caramel/extra cream, that have no caramel in them and they taste horrible. Management insisted they are making them the correct way, but they always taste horrible The previous McDonalds location I frequented , for the last few years before moving, always provided consistent coffees that had the ingredients in them that are expected when ordering these coffees. There just seems to be a lack of care and attention at this location. Hopefully management will take this review and use it to educate their crew. Its frustrating to pay for something over and over again that is less than satisfactory.

    Warning if you’re ordering through door dash. My experience is it’s always missing something or almost the whole order. Even though door dash refunds the consistency of incompetence is one thing you can count on.

    i ordered a small fry and 2 mnm mcflurry’s. the mcflurrys came and were not even half way full and barely had any mnms in it. the service at the window was not good. the girl was very rude, but the girl taking my order in the drive thru was very nice and had a good attitude.
