    Confused usually its open, but looks like its under reno. Large trash trailer next to it. And looks like a construction site today. Didn't go in - wasn't clear if its open or not. Website says yes...

    This McDonald's is a beautiful place to eat, talk, and play. However, I do not appreciate that on Google Maps it say they're open when they had construction and were actually closed. Or how they didn't put signs telling customers that they were closed. For example, around the windows or 24 hour open drive through sign.

    I bought a Spicy Mc veggie meal from this location and it was a complete waste of money. The Patty was so over cooked and burned i ended up throwing that burger away. It felt like it was either cooked a while ago and then re done just before the order or was just simply cooked too much to strip it off completely.

    McDonald’s is a great place to grab a quick and affordable meal. The service is fast, and the staff are friendly and well-trained. The food is good, and the prices offer great value for money!
