What people like to eat as a snack food varies wildly according to regional preferences and personal taste. What passes for good eats in some places in the world is considered quite repellant in others. Often, whether or not something seems tasty to you depends on what kind of food you had where you grew up. Comfort food means a lot of different things to different people.
In Korea, for example, dog is on the menu. Koreans consider it to be a delicacy, and there are restaurants that specialize in serving it. There are even canine farms where certain species of dogs are raised specifically for the food industry. In North America, thinking about eating dog is more than just unpopular. It is considered downright barbaric. Who would ever think about eating man’s best friend, right?
