So you'll see a lot of people with their tips mention how while Johnny Rockets for lunch/dinner has a cover charge, breakfast is included on Oasis class ships since there are so many passengers and it's an easy way to spread them out in the morning. Normal items like eggs and bacon or pancakes and french toast are all included.
But then they have 3 "premium specials" that have an upcharge, $8 if you get all 3. A loaded breakfast potato which sounds like just hash browns with cheese and bacon (the chunky kind of potato, not shredded) for $2. A breakfast burger which is just a burger with an egg/bacon/cheese on top, which makes sense bc it's a burger, for $5.
Then the Maple Bacon Shake which is a vanilla shake with maple syrup, whipped cream, chocolate sauce, more maple syrup and a slice of bacon for $3. It doesn't sound like it shouldn't be included with the beverage packages, but I've just never seen it mentioned and since it is listed as premium and not a beverage I don't want to make any assumptions
