A&W blueberry burger

Recently A&W released a new burger called bluebeary burger, it is burger that contains blueberry. I decided to buy one through food delivery, I order the one with beef meat.

When the burger arrived, you could see some blueberry above the lettuce. When I am eating it, the blueberry taste isn't strong and not very sweet. Overall, it feels average and no different from a normal cheeseburger because the beef and cheese taste overpower the blueberry.
