    Oh my god, there’s gonna be no more bacon cheeseburgers after this?

    Am I the only one that thinks A-1 is terrible?

    Ugh had the A1 Ultimate Bacon Cheeseburger tonight, so not worth the $5.89
    It was weak on A1 Flavor, meat was a good bit over the edge of the bun that was nice but it had the chemical smoke flavor.

    I’d be kinda interested in that SwissnShroom burger if it had their Mac Sauce rip off on it. Cant imagine their shrooms being any good though.

    Then again, Im obsessed with Wendy’s Portabello Bacon Melt.

      Yeah, was wondering if the mayo made any sense on the mushrooms. May have to try one with and another without mayo. It was funny since just today went by Burger King and they had the wording on the sign board. Thought it might be referring to two products then drove the lot and saw the posters. Already had KFC so maybe later.

        I tried the mushroom Swiss big king which I got in the two for $5 deal. Um you’re right…way too much mayo. I want to get it without the mayo next time and see how I like it. I particularly didn’t care for the third bun in the middle. I really miss the bk mushroom topper. That is definitely a favorite. Bring it back bk!

  5. Sascha says:

    Might be a couple of winners from BK here, though I might be tempted to remove the middle bun on the M&S Big King.

    This addresses a longstanding lack of A.1. sauce in the fast food industry.

  8. Axel says:

    I’d love to see a Big King with Whopper-sized patties called the Big Whopping.

  9. keefer says:

    I loved the BK Topper Mushroom n Swiss a few years ago so I am looking forward to this one! Probably the only Big King I will like!

  10. Jonathan Wayne says:

    As a single burger I might be interested, as a double it is too much.

  11. @homercles82 says:

    I had the mushroom burger the other day and, while it was good, the mushroom gravy combo was salty. Have a water ready, and maybe a banana lol!

  12. Scrape says:

    Always interested in a mushroom burger. Unfortunately, McDs got rig of theirs with the demise of the Angus line, Wendy’s is a seasonal deal (and lately hasn’t been very good), leaving only Hardee’s/Carl’s Jr. with a really tasty one. Although, as a step up, Smashburger has just introduced a REALLY good mushroom burger.

    Gonna have to try this one, but BK is kind of hit or miss with their specialty burgers.
