    Very clean restaurant. Good service and nice staff. Food came hot and we got everything we ordered. I'd definitely come here again.

    Ownership recently changed and it’s really gone downhill. Didn’t have Diet Coke and order was missing items or had incorrect items

    Excellent visit from start to finish. I ordered through the kiosk, which was intuitive and quick, and my food was ready in just a few minutes. Everything was made exactly as ordered — no missing items, no mix-ups — and the burger and fries were both hot and fresh. The restaurant was clean, staff seemed well-organized, and the whole process felt smooth and efficient. This is exactly the kind of experience that keeps me coming back to this particular location over others nearby.

    Really bad service has been a recurring pattern for us at this location. Tonight around 10 PM, we placed a small app order for drive-thru pickup. The lobby was closed and only three cars ahead of us, yet it took roughly 20–25 minutes to get our food. We sat at the speaker for about three minutes before anyone even acknowledged us, and each car seemed to take more than five minutes to get through. The worst part was the interaction at the window. The employee handed us our food without saying a single word — no greeting, no thank you, nothing. I finally had to ask, “Uh, is that everything?” She curtly said “yeah” without even looking at me. Customers should not have to drag basic communication out of employees. A simple “thank you” would have been fine; “Thanks, have a great night” would have been incredible at this point. And after all that, they forgot the sauces we ordered. We’ve had essentially this same experience here multiple times, so management has to know what the service is like. I’d genuinely encourage them to go through their own drive-thru one night as a customer and see how they like it. Terrible location.
