It does if you have like deli-thick slices of cheese... Like if you go to Wal Mart and go to the deli and have them slice your own cheese... Baby swiss, sharp chedder, etc.

American cheese, since it's typically what's put on burgers unless you go somewhere that gives you options (like cheddar, provolone, swiss) is a very mild cheese in general, so of course it won't add much flavor-wise to the burger... Unless you throw 2 slices on there, and then it just kind of. Seems off. IDK... I'm not a huge fan of American cheese at all. I'll use it in a grilled cheese with swiss mixed in, & my daughter likes it, but otherwise, I don't really use it.
