To me, it has the same flavor of the meat that surrounds the bone, but with perhaps a deeper flavor. No, you're not going to make a meal solely out of the marrow, but there is enough to eat. I recently had some from veal and from each chop, there was about 1/2 tsp of marrow, obtained by scooping out w/the back end of a spoon or fork. It is not a spice.

The best part about it is its consistency. So smooth.
