These three $2 were put on the Burger King menu about a month or two ago. How are they? Well, let me start with the Deluxe Cheeseburger.
The Deluxe Cheeseburger to me just seems like BK's way of making their own Big Mac... and I actually like it. It's a typical burger with cheese, lettuce, onions, and pickles, with a Thousand Island-esque dressing. The difference between the sauce on this cheeseburger and the Big Mac though, is that this one seems to be a little sweeter, which wasn't too bad of an idea. I'd probably get it again.
Deluxe Cheeseburger: 4/5
The Mushroom and Swiss Burger is very, very average. What you've got here is a burger with Swiss cheese, topped with sauteed mushrooms, and BK's "grill sauce." I feel like this would taste a lot better if its sauce had less salt in it. The mushrooms are what you'd expect from a fast food place (not very flavorful and sort of rubbery), and that's all that you really get from this. As said, this hamburger would be better if it just had a little less salt in the grill sauce.
Mushroom and Swiss Burger: 3.5/5
Finally, the Western BBQ Cheeseburger. This one intrigued me most - not because it was at all a unique idea, but because I've always liked somewhat out-of-the-box burgers like this one. This one is just a hamburger with BBQ sauce, cheese, and onion rings... and it's good. It's nothing most people haven't had before, but it tastes alright, and that's really all that matters.
Western BBQ Cheeseburger: 4/5
All three of these are pretty decent, but the thing is, $2 almost seems too much for these things. The size of these are about that of a Whopper Jr., to give you an idea, and it's not like there are little gold flakes on here that make these worth a dollar more than the Whopper Jr. But if you want something somewhat different at Burger King, try either the Deluxe Cheeseburger or the Western BBQ Cheeseburger... they're not too shabby.
