Hot Off the Press also has smoked salmon and cream cheese on a piece of rye toast, which was surprisingly good (and honestly I think cruise line bagels are mostly meh so this as better).
My favorite brunch item was the Burger Bar's French Toast Burger, partially because of how good the French Toast was....
A recommendation: if you're doing a lot of reservations for a lot of people, type up a list ahead of time of the names and room numbers what you ideally want which day (and a 2nd choice) to make it considerably faster and easier for the person processing it (which will get you better reservations)
Oasis ships have the branded Starbucks locations but all ships including them also have one or more included coffee shops (Cafe Promenade or some equivalent) that are included in your beverage package.
