Random thoughts about breakfast nooks
You can simply have your nook in front of the window. Because you can actually move it to access your cabinet, this will not be a problem. Of course it is best to use those cabinets for the things that you do not use everyday, for your convenience. Now, depending on the style that you want and how big your space is, you can have a small nook with just two benches facing each other or you can have the typical corner nook with L shaped seating that are used commonly used in restaurants and diners. Between the two benches, place the table that matches your benches.
