The first day of McDonald's national roll-out of its all-day breakfast is here, but before you get your hopes up, here's what you can and can't order. 
 
 The long-awaited menu for breakfast fans will vary by location. For those who love McGriddle sandwiches, you're out of luck. That item isn't a part of the all-day breakfast menu in any markets, so you'll be skipping on those 450 to 570 calories. Bagel sandwiches, cinnamon melts and "Big Breakfast" platters aren't included in the all-day menu either. 
 
 1. In most markets, you can order: 
 
 - sausage burrito 
 
 - "Fruit ‘N Yogurt" parfait 
 
 - "Fruit & Maple" oatmeal 
 
 - hash browns 
 
 - hotcakes 
 
 - hotcakes with sausage

 2. In markets that offer McMuffins, you can't get the Egg White Delight or the steak, egg and cheese McMuffin, but you can get: 
 
 - egg McMuffin 
 
 - sausage McMuffin with egg 
 
 - sausage McMuffin 
 
 3. In markets that offer biscuits, you can't order the "southern style" chicken biscuit, but you can order:

 With so many options, breakfast has never been tastier. We know you've been asking, so the All Day Breakfast menu is here. You can enjoy Hotcakes, a savory Sausage McMuffin with Egg or Sausage Biscuit any time you want.* You can still enjoy our full breakfast menu every morning, which includes favorites like the signature Egg McMuffin or the sweet McGriddles. 
 
 
 
 * Menu items vary by location. Deliciousness doesn't.
– The highly anticipated all-day breakfast menu at McDonald's is debuting nationwide Tuesday, but not everyone's morning favorites have made the cut, ABC News reports. Those who are jonesing for the chain's hash browns, hotcakes, fruit and yogurt parfaits, oatmeal, and sausage burritos are in luck—as are those who want a plain egg or sausage McMuffin and most egg-and-biscuit sandwiches. What aren't included: two specialty McMuffins (the Egg White Delight and the steak-egg-cheese variety), the "Southern style" chicken biscuit, bagel sandwiches, cinnamon melts, and, alas, the maple-infused concoction known as the McGriddle. And those who have a huge appetite may need to supplement their breakfast sandwich with a Big Mac as the day drifts by: "Big Breakfast" platters aren't an all-day offering, either. (There's something else you should know about McMuffins.)
