Brioche bun served w a beef patty, cheese, caramelized onions, mushrooms, arugula, truffle oil & mayo. Nothing special about this burger, the truffle taste didn’t really come through & the arugula didn’t really go well w the burger as it left a bitter aftertaste (would have preferred the normal lettuce instead). Beef patty was slightly chewy (not the soft beef patties that I love) & it wasn’t as flavourful. It also came w a side of potato chips & salad. The salad was disappointment bc it was just a bunch of plain lettuce (we couldn’t taste the sauce at all) & the potato chips were just your typical lays salted chips. Would not recommend this but luckily there was 1 for 1 on entertainer!
