I tried to include as many toppings I could think of that most people may think to put on a burger, however I realize some people will combine almost anything with anything, so make liberal use of the “Other” option if you must.
I like a fairly standard bacon cheeseburger.
American cheese, bacon, raw onion, lettuce, tomato, ketchup, spicy mustard, top off with some hot sauce on a good sesame seed bun. Sorry to be boring.
Perfect hamburger for me:
Lightly toasted bun, medium burger, American cheese, ketchup, mustard and pickle relish and cooked onion.
Toasted sourdough texas toast, burger, light salt, pepper, lettuce, tomato, bacon,cheddar cheese, dab of catsup.
Bacon (thick slice!), blue cheese, grilled onions, and mushrooms. No condiments.
Do NOT ask me what my cholesterol level looks like. :rolleyes:
I can’t decide. 
One day I may be in the mood for a good ol’ bacon cheeseburger, the next day I may want a feta/avocado/onion combo more.
You left out rolls. Do we have to put our burgers on ordinary blah hamburg rolls? I’m using marble rye because it’s basically a patty melt.
Bacon, ketchup, cheese. Not that particular about what type of cheese, but cheddar is pretty good, so I put that down.
Bacon, blue cheese, sauteed onions and mushrooms, on a buttered, toasted kaiser roll.
Caramelized onion, avocado, tomato, lettuce, mayo and ketchup
I like them a lot of ways, but must insist no ketchup, mayo or mustard. Leave those out and we’re cool.
I’d like mine w/oniontomatolettucepickleketchupmayoandspicymustard, thanks.
There was a burger joint (Smashburger) that, upon its debut, offered spinach instead of lettuce on the burger. An option I always took. Apparently, nobody else did.
C’mon, people! Spinach on a burger tastes exactly like lettuce on a burger, except maybe with less snap, and more vitamins and that good stuff. I mean, it could be an option, right?
So that’s my “other.”
My ‘dream burger’ is pretty simple: a good-quality patty (no bigger than 1/3lb, please) on a lightly toasted bun, cheese (I picked cheddar and Swiss from the list), bacon, dill pickle chips, and then the “Other” ingredient is A-1 steak sauce.
Cheddar cheese. Raw or cooked onion (I have no preference). Pickle. Fried Egg. Mustard (I actually like plain yellow mustard in this case). Ketchup.
edit: I should add, the main reason I eschew lettuce and tomato is because, invariably, it’s terrible lettuce and tomato that find their way on a burger at most burger joints.
The best damn burger in town is done medium-rare on a good hefty bun that doesn’t turn to mush in the face of drippings. As for toppings, it’s got lettuce, tomato, mayonnaise, and an incredible local mustard called “Lusty Monk.” They serve it with freaking amazing fries and good pickles. I only eat a few of them a year, but goddamn.
I did a bacon cheeseburger with onions, but really, the perfect burger isn’t what’s on it, it’s how it’s done. If I had nothing but a beef patty and a bun, if it were gooood beef and goood bread, it would be the prefect burger. Conversely, onions aren’t going to save Mcdonalds.
A-1 sauce has been my burger condiment of choice lately. No, I don’t put it on steaks.
So, lettuce, tomato, cheddar or American, grilled onions, grilled mushrooms, A1, and (if I’m in the mood for it) bacon, sesame seed bun.
That said, there is a time and place for a BBQ burger (with onion straws) or a black ‘n’ bleu burger if I’m in the mood for one of those.
beef, lettuce, tomato, ketchup. Mayo is optional. Onion is OK. Swiss if someone insists on cheese, though I’d prefer Emmenthaler or Jarlsberg (which are Swiss, but actually have flavor compared to hamburger joint Swiss).
I’m not sure I can vote. Can I choose every single option?
There was a long-running bar & restaurant in the Nana Plaza red-light area called Woodstock Bar. They had what was called the Mad-Hatter Burger. It had everything on it, and I mean everything. Big meat patty (forget the weight but large), fried egg, sausage links, bacon, ham, several types of cheese, onions, lots and lots of fixings. It stood very tall on the plate. I could eat one and not have to eat again for 24 hours. That was a great burger.
Woodstock eventually moved off to another part of the city and no longer offers that. But it stopped serving it even before it moved, once when it changed ownership. That was almost 20 years ago, and I still remember that burger. Mmmmm.
