McDonald's (NYSE: MCD) popular all-day breakfast options were taken off the menu back in March to help simplify and speed up the ordering times amid the coronavirus pandemic. Fast-forward six months and McDonald's still has not brought all-day breakfast back to the menu, even though some other items that were also removed at the time are now available again. After years of consumers clamoring for the ability to order a McGriddle at 4 p.m., McDonald's launched the all-day breakfast menu in 2015 to great fanfare and it snapped a two-year slide in same-store sales.
