As well as that, several menu favourites are back, too. Milkshakes, Bacon Double Cheeseburgers, Bacon Mayo Chicken - as well as ordinary Mayo Chicken - and hot chocolate.
So, the actually numbers behind the reopening are relative complex, as it's been a bit of a mish-mash of reopening for take-away, delivery, and all sorts.
To be fair, everything has been a bit up-in-the-air of late, it's forgivable.
The take-home message from it all is this - every McDonald's restaurant with the exception of 28 are going to be open for breakfast starting today.
That means that there is a fairly good chance you'll be able to find somewhere to get a McMuffin, a McBacon Roll, or whatever it is that you fancy - with a few exceptions - that can only be procured in the morning at Maccies.
Rather than listing all 1,301 restaurants that are offering the service as of tomorrow, it's probably easier to count the ones that aren't.
Whilst that would certainly get through some word count, you can head on over to the My McDonald's App for the hard details.
A McDonald's spokesperson said: "We have seen such a brilliant reaction to breakfast in the first 42 restaurants, the return of the McMuffin is proving incredibly popular."
"We are therefore delighted to confirm that over 1,250 restaurants will add breakfast to the menu from tomorrow morning.
"Our menu will still be limited, we will unfortunately not be serving bagels, wraps or porridge for now.
"Our opening hours continue to vary, the quickest way to check your local restaurant will be via the My McDonald's App, where new users can also get a free coffee upon registration."
This is still all a bit piecemeal and complicated, but - as we've mentioned earlier - if you head on over the My McDonald's App you'll be able to easily calculate where you're headed off too for your fix.
Some will just be doing so as a takeaway, but with extended menus that include breakfast. Some will be offering a delivery service, and some - get this - you'll just be able to walk straight into and order your food, almost like in normal times.
Speaking as the reopening began recently, McDonald's UK & Ireland CEO Paul Pomroy said: "It's been over 100 days since we temporarily closed our doors.
"In that time, we've donated over 500 tonnes of food to charities and food banks, distributed 100,000 litres of milk and supplies to key workers through charity partnerships with Food Drop and FareShare, and in the last 40 days, we have reopened over 1260 restaurants with tens of thousands of our employees returning to work."
"We are delighted to be back. We continue to see such a fantastic reaction from customers across the country, and we are so grateful to you all for the continued support.
"As ever, the safety of you and our employees comes first, so we are making gradual changes that we are confident still enable us to prioritise that safe working environment.
"Our ability to introduce some of these changes may also be impacted by factors specific to where certain restaurants operate. As always, we will continue to follow government guidelines."
