Road Trip!

This summer my brother and I will be traveling cross country! He's moving to San Diego, California, so I'm helping drive him there starting from Pensacola, Florida. We're both foodies (he's the cook, I'm the baker) so we're looking for places to stop at along the way.

Does anyone have suggestions for bakeries or restaurants to visit? We will be passing through Houston, Austin, Killeen, Baton Rouge, El Paso, Yuma, Las Cruces, and Phoenix, and all places in between. We're also not set against reasonable detours.
