Had breakfast 2 days while staying at Delta. Better than concierge level where food was sent up early in the morning and not refreshed as often (or cooked in front of you).
Husband had the salmon which he liked. I had pancakes, yoghurt and fruit from the buffet. Our 2 year old had hard boiled eggs which he loved. Great accommodation for the family. Nice staff. Can't beat complimentary food as a Marriott member.
