All-day breakfast at McDonald's is officially here, but it's not being welcomed by everyone.
The fast food chain dominated Twitter's trends with #AllDayBreakfast on launch day Tuesday, but received some hilarious tweets from breakfast icon IHOP.
The breakfast chain, open 24 hours in many cities, took time to share how they felt about the McDonald's move on the internet.
The posts progressively became bolder (and more funny) as the day progressed.
Most, but not all of McDonald's breakfast menu items will be available all day, the restaurant said.
The company has been trying to boost recent sagging sales and ramp up their morning menus.
