    Got a quarter pounder, with only ketchup, no cheese, but got a quarter pounder, with no cheese, onions, pickle, and ketchup. Messes up my order every time I go. Sometimes it feels like the worker only reads "Quarter pounder w/ cheese" and then makes it.

    With fast food things are typically hit or miss. We try not to eat out too often because how unhealthy it is, but sometimes life makes it the only option for the day. This McDonald’s location never ceases to amaze me with how consistently bad it is everytime I’ve been there over the years. I’ve given it countless months and convince myself, surely it has gotten better. Everytime I’m wrong. The fish sandwiches are always rubber or hard as a rock, the fries consistently stale, and nuggets are either stale or soggy. It’s unfortunate the price of things keep going up, but quality only seems to ever go down. Do better McDonald’s.

    This is truly the worst McDonald's. Not only did I have to wait for my drive thru order for 30 minutes, once I finally got it, my fries weren't even room temperature. They tasted as if they'd been sitting there for hours. Then I asked for fresh fries, and I received fries redipped in oil and given back to me. Such an awful experience.
