When I want a really meaty burger at McDonald's, I order the Double Quarter Pounder Cheese! It's on the pricey side, but it's a burger I personally like.

Compared to the regular Quarter Pounder Cheese burger, you need the double patties to really feel like you've eaten a proper hamburger, so I always get it double — it has a deep, intense meaty flavor and is very filling! However, there are almost no vegetables, so it can feel a bit greasy and tastes may divide people, and because there's little sauce to begin with it can feel slightly dry while eating, which is a bit disappointing T_T
