You won't try any foods at all? How do you live! :(
I don't have any problem trying new foods regardless what they are. There are probably some extremes that I wouldn't try such as caramelised cow dung or whatever, but I'll try the huge majority of things. Chocolate crickets are yummy and crunchy, the common "eww" foods like snails and frogs are very tasty (not meaty enough though!) and things like sweetbreads and offal are fine as foods and are pretty tasty, but I'm not a huge fan of the texture. As long as it's safe to eat then I'm happy to try it.
EXTREMELY reluctant. Considering I'm quite the picky eater, trying 'delicacies' is simply out of the question. Any types of bugs, chocolate-covered or not, or internal organs such as liver or intestines make me very uncomfortable even just thinking about eating them. Texture and smell play a huge role as well.
To say I want to make it my life's mission to visit The Fat Duck at least once in my life is an understatement! Just have a look at its menu! For less 'out-there' types of food, I'm still normally up for anything. Exotic meat, especially. For me, presentation is key when it comes to trying new foods: if it looks appealing and I've never had it before, it's probably going to go over a lot better with me than if it looks fugly as hell.
