I'm surprised this one doesn't have a thread. It's one of the best food shows on TV.
The visual quality isn't as superb as it should be because I have Dish. However, food--especially things with various or unusual textures (by US standards) stand out quite a bit with the extra resolution of high definition.
Weirdest episodes? For me, it would be a toss-up between Uganda and Canton, China. Honorable mentions to Japan, the Gulf Coast of the US, Alaska and Ethiopia.
