I did a built in curio cabinet in a dining room with chair rail once. I used birch ply for the top, which sat at the same height as the top of the chair rail. I used a piece of the chair rail molding (ripped down to 1 1/2") for the edge of the counter and coped it in to the wall rail for a seamless transition.
The molding was glued to the counter edge with epoxy, to eliminate the possibility of the joint cracking in the future. Use the epoxy to fill the joint between the molding and the top, sand flush, and paint. Invisible.
