Maybe it's just those of us who don't have cable that watch these?
My favorites, which are cooking/travelogue combos that give history of the areas and and may visit markets, restaurants, food/wine production places:
Spain On The Road Again (Spanish food, and Mario Batali, love him ), only 13 episodes so far, though. This one may be an acquired taste (pun intended), but it's high on the entertainment factor and excellent music used. My only gripe about it is that when Spanish is spoken, there often aren't enough subtitles. I can pick up some of it without them, though.
Perfect Day (mostly Scandinavian and other European food) - usually outdoor cooking in beautiful settings.
New Scandinavian (just Scandinavian) - often outdoor cooking, and again, beautiful settings.
Lidia's Italy (Italian) - lots of veggie dishes, but some of her stuff is very labor/time intensive.
I also like:
America's Test Kitchen - they're good at researching and testing "the perfect fill-in-the-blank".
Joanne Weir - lots of veggie dishes
I'm amazed and inspired by much of the cooking and get a lot of ideas.
