This item is on the new BK value menu. It sells for $1.39 plus tax.
Non-customized burger consists of a small patty, barbecue sauce, and three onion rings. It is not very filling (but touted as a snack) and is tasteless due to lack of condiments. The barbecue sauce just adds sweetness, not flavour. The two times I ordered it, the onion rings were missing.
For 20 cents more, you might as well get Whooper Junior.
