I might be missing something, but those look pretty ordinary.
Here in the UK, there was a bit of fashion for upmarket burgers about 10-20 years ago and so various chains (Byron probably the best well known) expanded to fill the niche, but it seems once the more innovative and stylish hipster independent burger joints got going (and for about the same price), many of the upmarket burger chains got caught as an unappealing middle ground and have been gradually going to the wall.
Those are just the buns.. they make fresh buns everyday, most burger places don't really do that for their prices. For most people though it is their burger seasoning and Jalapeno Cheese as well that they like.
*Wonders about UK Burgers* when I visited the UK, the burgers I had there were pretty bland, but most of the food was compared to Texas peppers and seasoning I am accustomed to. When I look over the UK top 50 burger places, I am not seeing these fresh ingredients like fresh cut fries and onion rings and the burgers look really greasy. To me that makes a burger worse, not better so maybe I am missing something. To me, just piling more weird stuff and more patties and such on a burger makes it gross, not better though.
I like a burger that is juicy, flavorful and well seasoned. Cayenne pepper is a must. Where the juices STAY in the burger, not all over me, freshly made, grill toasted buns, , crisp,lightly colored, flavorful seasoned pickles, and a good selection of cheese. Freshly making all fries and onion rings with NOTHING frozen. Onion rings must ALWAYS look like this:
and NOT like this ewww gross stuff:
Are there better ones than this list?
Nothing beats a good burger; it’s often one of the first things we reach for when arriving in a new city. So where are the best burgers in England?

Now there are some good looking burgers on that list, but most of them are just junk piled high and I have no use for that. I just want a good tasting burger. If I want the other stuff, I would look for the other stuff, but I DON'T want all that other crap on my burger. I can do without a lake of grease when I eat. If it is well seasoned and evenly cooked it will have more than enough juice inside and the flavor stays in the burger, not on my dress.
