A bigger Big Mac is expected to make its debut in Bethesda today. The McDonald's at 5214 River Road will begin serving the Grand Mac today, according to an employee.
Grand Mac features all of the standard Big Mac ingredients, but in greater size and quantity. McDonald's is using the classic, thin burger patty, not Quarter Pounder or thicker patties, as some early reports claimed. The burger is simply wider, rather than thicker, as are the buns and cheese slice.
I managed to locate a Grand Mac early, at the McDonald's in Derwood yesterday. Here is my review of the super-sized Grand Mac.
