    Worst experience ever! Told to pull forward at drive thru even tho no one was behind us. Waited for over 10 minutes and finally went inside myself to get my food. 2 cars that showed up in drive thru went by us with their food while we were waiting. I believe I would've waited another 10 minutes if I hadn't gone in. Did not get any monopoly pieces as well. BTW, ordered a big Mac meal and a Mcdouble. I will never visit this location again.

    I have had really terrible experiences at this McDonald's. There is No Parking, terrible customer service, and they charge for each sauce, unless you buy chicken nuggets, then you can have 1 for free.

    So disappointed, on my way to work and I passed to this location to grab a meal and they said it was closed. It supposed to be a 24 hour open. And it happened frequently it’s not the first time.
