I love their shakes and the summer time special for 1/2 off after 8 PM.
Having said that the service is slow and quite often they get the orders incorrect. Don't over complicate your order with too many customizations, because they will just ignore your requests. By the time you get home you can't be bothered to do anything but eat whatever they shove in the greasy bag.
The food is delicious, but overpriced for fast food. To their credit they do have a value menu with yummy bites like a grill cheese for $1.49. A corn dog for .99 cents or a chicken strip sandwich for under $2.00. Also on Sunday they have a $5.00 chicken meal. Other than that, be prepared to spend $7.00 and up per person.
Also, if you pull into the slot and order from the car, it's encouraged to Tip the service folks.
