It's annoying that you can either choose between having a weedy shit burger that's mostly lettuce and has to be held together with a stick, or eating a really expensive one and have to look at a load of wanker tat on the walls.
Also, you can stick your brioche buns up your arse. A brioche bun is not a load bearing bun. It dissolves in contact with moisture.
Hold on, a brioche bun can totally work! Toast the bun, put a little mayo on it, put the veggies on the bottom (at least the lettuce), and a regular-sized burger will hold up just fine.
Not saying it can't go wrong, especially in a place that just wants the decor and the food to look good on Instagram even if it's disappointing when you bite into it. But for burgers I've made, a brioche bun can be a nice option. :P
Also why do Americans like mixing sweet and salty. Here in Australia they have brioche buns everywhere now. I hate that crap, if you don’t have normal buns give me two slices of bread instead
