If you have 15a receptacle circuits in a dining room it is a violation. They do have to be AFCI tho.
OTOH a "breakfast room" may not need AFCI.
210.12 says "dwelling unit family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas <need AFCI>"
Is it similar to a kitchen or a dining room?
