One of my favorite tags to surf is food. As cliched as it would be to say it makes me hungry, I am in fact really hungry right now.
Perhaps my favorite food-related series on Flickr is Pahtz‘s “cheap eats”: inexpensive food found in Hongkong. They aren’t all tagged, but a quick search finds them all.
You may notice that asian cuisine is over-represented, but food photos are a big thing – we hear that Japanese digital cameras often have a “food” setting.
