Today, CNN Money's Laurie Segall reports on 4food, a new New York City restaurant that's fueling its customer base with the use of social media. The restaurateurs claim to offer 96 billion burger combos available as orders. Stacy Cowley crunches the numbers.
New Manhattan burger joint 4food lets eaters customize their creations with an extensive ingredient menu, and news reports have put the range of options at anywhere from "more than a million" to "140 million" burger combinations.
"There can't possibly be 140 million combinations," I said to my statistician spouse.
"Let's find out," he said, firing up Excel.
Here, based on the menu on 4food's website, are the parameters we started with, and our assumptions:
5 buns [breakfast bagel, brioche, multigrain, pressed rice, pumpernickle]: Have to have 1
4 add-ons [lettuce, NY pickle, tomato, onion]: Can have 0-4
12 condiments [mustard, guacamole, bbq, horseradish, hummus, jerk sauce, tartar sauce, mayonnaise, ketchup, salsa verde, sweet chili, tzatziki]: Can have 0-12, should have 0-3
7 cheese [blue, goat, fontina, gruyere, manchego, mozzarella, cheddar]: Can have 0-7, should have 0-2
4 slices [avocado, pancetta, mushroom, sopresatta]: Can have 0-4
17 scoops [avocado & chili mango, baked beans, grits, hominy, fruit & nut, edamame, egg, mac & cheese, mofo, mushroom & onion, peppers, chorizo & potato hash, brussels sprouts, spinach, veggie chili, veggie sushi, winter slaw]: Can have 0-1
8 patties [beef, breakfast pork, egg, lamb, pork, salmon, turkey, veggie]: Can have 1
Using that, we ran two formulas. The first calculated how many choices you'd have if you stuck with "should have" - no more than two cheese slices, three condiments, etc. That gave us this:
5 * (2^4) * (12C3 + 12C2 + 12C1 + 12C0) * (7C2 + 7C1 +7C0) * (2^4) * 18 * 8 = 1,598,238,720
... which is 1.6 billion combos.
But if you take off all sane restraints - want 12 toppings and 7 cheese slices? Sure! - and allow all theoretically possible combos, you get this:
5 * (2^4) * (2^12) * (2^7) * (2^4) * 18 * 8 = 96,639,764,160
... which results in more than 96 billion combos. Jam that on your leaderboard.

This post could not be more right on..
Very well executed article..
Where is the BACON ?!?
Where is he bacon ?!?
Hopefully liveobxhwy12 comes back to learn the simple difference between the number of COMBINATIONS that can be chosen/ordered, and the fact that no two burgers will be EXACTLY the same. (I particularly liked TSmoov's knocking off the sesame seed point.)
Heck, using liveobxhwy12's reasoning – or lack thereof – even the hamburger at McDonald's approaches an infinite number of variations. But it has only has 8 or so combinations (w/ and w/o mustard, catsup, pickle, ??). 1*1*2^3. (Note: if you have McD's put cheese on it, it's a different menu item.)
