When we first moved into our home we had the builders add a drywall soffit above all the cabinetry with plans that we would one day add crown and other trim work to it. While we had the dining room finish work done we had them complete the kitchen soffit as well.
It is 3 pieces of trim - crown, a baseboard hung upside down, and pin mold at the bottom of the soffit.
We had them trim out the windows as well.
By the Way - The new white leather barstools from Target are holding up great so I think I'll be stenciling them soon (well, kind of soon)!
