Actually suites have an expanded room service menu for breakfast, including more hot choices. Suites can also get room service on disembarkation day, which is not available to other cabin categories.
Having access to the full dining room menu for evening meals is one our favorite suite perks! We love dining on our balcony and don't have a problem with everything delivered at once.
Edit to say I have my own copy of the suite room service menu, but rather than dig it out I just did a quick Google image search for this example. You can search that way too for regular and suite room service cards.
