The Suite Passengers are entitled to full cooked to order breakfast. I think concierge level also gets room service. Otherwise, I don't know what the breakfast is for standard cabins. I would not go with less than a concierge cabin.

We met a couple in a concierge cabin. The room was very much like the PG cabin but shower without a tub. We had a full bath with the shower over the tub. Our room was 322 sq ft while their room wasa bout 200 sq ft with veranda. They got room service but a slightly more limited menu.
