A bacon burger with mayo, sauteed onions and mushrooms from Five Guys

I've been curious as to how the burgers at Five Guys would taste like without cheese because I haven't had one. This was it. Just like how I was curious previously about how Shake Shack burgers would fare without cheese. Aside from a getting a cleaner mouthfeel with the meat, I don't think I liked it better. So it's gonna be back to cheese burgers again in the future.
