Guthrie's has a simple menu. You can either get the box or the sandwich. The sandwich is a chicken tender sandwich & the box contains bread, fries and chicken strips. What makes this packed around 2AM is everyones' craving for that special, secret sauce. This mayonnaise based sauce is difficult to reproduce so don't try to make it at home. It's open until 4AM but it's drive-thru only after 2. Also be prepared to wait for a LONG time if school is in session as the cars will be backed up to the TCBY.
