This is a perfect combo of my two favorite ideas for that space under the stairs leading to the basement. A reading nook AND book storage and shelves . assuming that there is enough space for this there.
This bookshelf wall is the dream of every bookworm. How else will you store all your books in your dream home or interior? I always love when bookshelves go over a doorpost and all the way to the ceiling.
Use the back kitchen for everything breakfast. Tea, coffee and toast making. Cereal getting and all the cutlery and dishes that get used at breakfast. Then you do not mess your main kitchen until the serious cooking starts later in the day.
