What they recommend is the 100% wagyu burger or the roast beef.
Crispy and not too dry pretty ok.
Its pretty good but I think the one I ate in japan tasted better. The meat tasted flavourful and it wasn’t too hard. I ordered the xl version and the meat was plentiful.
But My friends didn’t think it was that good. I think it doesn’t melt in your mouth as much as you think it would.
