Gwyneth Paltrow, acclaimed chef Mario Batali and New York Times food columnist Mark Bittman are embarking on a road trip that boasts slick cars, hearty food and a candid camera monitoring the flashy travelers.

Paltrow, the duo of American food gurus and Spanish actress Claudia Bassols announced their journey, which will be captured in a 13-part TV series, "Spain ... on the road again."

The series, which is designed to give viewers a closer look at Spain's cuisine, wine, culture and nightlife, will air on PBS next fall. The four celebs were to set off today and spend much of the next four months sampling the best fare in a country that usually ranks as the world's second most powerful tourist magnet, after France.
