The chairs are modeled with the seat being 18 inches wide, and 20 inches deep,
which is pretty much what the chair I am sitting in now measures.  The lens I'm
using (camera35mm.inc) is 24mm, so moderately wide-angle, which may be the real
cause of the issue.

There are other comments about the chairs as well.  They probably need a curved
back, maybe a little higher back as well to look comfortable.  The seat probably
needs to have some body-conforming indents as well; flat wood seats are not
terribly fun to sit in for long.

Well, if you come to my house, I won't serve you champagne in my flutes.  Mine
are those dimensions exactly, so you probably wouldn't like them.  ;-)

I have a few comments on the chairs, so I may revisit those as well.  I didn't
have a real-world model for them, just some basic dimensions from chairs I have
around the house, and a desire to not have them extend to high above the table
and ruin my line of sight to the table setting.

There was a model for the silverware from an online restaurant supply store, but
I didn't read any reviews to see if any restaurants actually chose that version
and liked them.  At that point I was probably looking for simpler handles,
rather than usable ones.  If I go back for another pass to fix other issues,
I'll revisit those as well.

The radiosity may not be needed because the ceiling lights are spread throughout
the scene and provide pretty good coverage.  I'm still going to play around with
a radiosity-only version and a mixed model because it sounds interesting and
would be something interesting to learn how to use better.
