I had MuckDonalds via Uber again last night
i found a menu option that turns a double cheeseburger into a 1/4lb'er with cheese...
the only real taste difference between the two are the onions, dbl cheese has tiny little bits whereas the 1/4lb'er has fresh onion,
in the toppings options you can remove the onion, then add extra fresh onion and it makes a world of difference, tastes exactly like the 1/4lb'er for less than half the price!
Just did this with a triple, can confirm it makes it a lot better and similar to a 1/4 pounder.
