    My burgers were fine, but my French fries looked like a new seasoning which I know was not the case so assuming their grease needs to be filtered and cleaned. Fries themselves just had no taste or salt despite. Then I went to drink my sweet tea, super bland and bitter tasting, like the pot was dirty/tin was dirty/old. Overall not their normal service and food quality, dissatisfaction for sure.

    My wife just went through the drive thru for a cheeseburger happy meal for our daughter. Drove home only to find out there was no burger in the happy meal. Unreal level of incompetence, great job! 🫡

    I've gone to this location several times in the morning to have quick meetings. They are always cleaning up to start the day & the service is quick, courteous and professional. The manager often brings out the food and greets customers personally herself.
