I bought one for $1.99 (which is also the same price as their new Hot Chicken Sandwich).
My burger came straight from the warmer, which makes the pickles an odd inclusion. I don't know how long the burger had been sitting there but the moisture from the pickles soaked well into the bottom bun and left it a soggy mess that barely managed to keep together. The top bun was light and squishably soft. The pickles themselves lent a contrasting acidity that you'd normally get from ketchup or mustard.
The cheese was the most memorable component as it was thoroughly melted and quite tasty.
