Mirrors in a foyer serve two major functions: 1) as a way to widen the visual space of the room by creating an expanding view of the walls beyond and 2) to provide yourself and guests with a place to double check their appearance before leaving or entering the rest of your home.
There are a lot of ways to use mirrors in a foyer ...

You can make a big and artful impact in a foyer by layering or hanging multiple mirrors on the entry wall. In this case, the frames are all the same hue, while the mirrors are different sizes. I think this combination works best.

Another option, and one that you might want to choose if you live in a home or space that doesn't have much architectural interest, is applying several mirrored squares to the wall in your entry and then framing it with mouldings that coordinate with your existing. Using mercerized or antique mirrors for this process gives a great look.
If you don't want to go through the process of applying mirrors to your wall - you could always find a very large mirror to hang or lean behind an open leg console table:

It's a great option to not only expand the width of the space, but also the height - visually speaking. Of course, there is always the most traditional option:
