Burger King

I really like the tacos at BK but the ads and photos show shredded cheddar cheese. The location in Waterloo IL just throws a slice of American cheese on theirs which is just not right. Cheddar would really taste better and is traditional for tacos. They have shredded cheddar available because it's on their salads. I don't know why they don't use it in the tacos as they should. I asked the person at the register about It and she told me they did use cheddar, but it's nothing but a slice of American cheese. It's been this way since the tacos came out. I don't get it. It would be nice if somebody could address this with the manager.
Thank you.
