Bobby vs McDs is not the same game. The cheapest burger+fry price at Bobby’s is roughly 10 bucks. Absolutely no comparison with McDs. 10$ burger fry opens up a lot of competition and I personally think Bobby’s ain’t so hot in that price range.
Having said that, only in a few instances would I want a Bobby’s burger over something like an In n Out 2x2 animal style.
I do like crunchifying in general. I put fries in my burgers at White Castle and like my subs with some fries crushed into it.
