Just thought that I would share with you all a great and inexpensive place to stop for eats on the NIV (Andaluc�a) about half way between Madrid and Sevilla.
"Casa Chavez" is the name and it is on the NIV (Nacional IV) highway exactly at the rest stop at kilometer 280. You can only access it heading south since on the north side there is a different place that is unimpressive.
Casa Chavez is a good place for tasty, inexpensive food and a nice rest on the way down south.
