Though I'm not from England or any of the surrounding parts, I've been there in the past, quite a few times on business. All these variations of the "Full Fry Up" mean there will be arguments as the "best". Personally, I didn't find a Fry Up that I didn't like. They were all great. Pity we never adopted them here in the States. So, I'm not seeing what the fuss is about as to "best".
Here in the States, there's diversity in regional breakfasts, and again, for the most part, except for certain chain restaurants, they're all pretty good if prepared by a competent chef/cook.
Yes, I'm one of those who try almost anything once as long as a) it's dead and b) not staring at me. And I'll have it twice (or more) if I like it.
