Make sure you read the terms and condition with each offer. You always have to spend more than the $25 amount, but the amount will vary depending on the certificate.
I just purchased 4 certificates (the maximum allowed) to the Eggspectation in Gainesville.
Eggspectation is brand new to restaurant.com so you may want to purchase these before they are gone. With the Eggspectation certificate you have to spend $35 to be able to use the $25 voucher. So if you take into account the $1 certificate price you are really getting a $35 gift certificate for only $11 plus tax and tip! That's a great deal. I'm wondering if this can be used in conjunction with their "Kids Eat FREE" Monday promotion. Wouldn't that be sweet?
