Most people would be putting in a central light over the dining table in this situation. The chandelier or drop style of lighting fixtures would be most often used.

I've sat in numerous restaurants that have installed downlights over their tables. That style of lighting is very harsh as it creates shadows on diners' faces -- and everything on the table -- accentuates every facial imperfection, and is just annoying. I think a chandelier is better because it hangs lower, and the light is less directional or can be more easily directed at the tabletop.
