- AHAmber Hull1 day ago1.0Forget part of the order every time. What food that is correct is cold half the time. For some reason, shakes seem to mean flavored milk, and the fast is missing from the fast food. The only consistency from this location is their ability to disappoint. Service is at least mostly friendly.
- RGRoderick GrayFeb 15, 20261.0Very unprofessional…I turned food down based on appearance of the workers… very unclean looking..
- KMKathy MadereFeb 6, 20261.0Went on my lunch got the #1smashburger and it was absolutely nasty. So greasy and cold. The fries were also cold. Only thing that was actually ok was the strawberry lemonade.
