The McDonald's Big Arch is a lot of burger at a high price. I can't say this is a good deal. There is a lot going on for that price starting with a poppy and sesame seed bun of solid quality.
You folks know how much I hate bad buns.
Then you move on to the shredded lettuce that gets all over, slivered onions, and pickles. These are all things I would have off the burger because it's size will wilt the lettuce, I get sick if I eat raw onion, and pickles just have too much salt.
As for the two burger patties and cheese, well, it's the wrong cheese. Not enough flavor in that cheese to be worth it. The two patties are bigger than standard clown burgers but still not all meat. They have additives, and I can tell.
Then you have the sauce and crisp onions. Both kind of get all over, but add to the overall flavor of the sandwich making it better.
This is a lot of burger and sure edible but nothing to write home about. I found it satisfying if not great.
