I can't imagine the under-underpass business units are all that pleasant to work in, but who knows? I've never been inside one, unless you count the Lockside restaurant, which is actually very nice. One of the upsides of being under the underpass is that you don't have to look at it.
I understand that Guy de Maupassant ate lunch at the Eiffel Tower every day because it was the only place in Paris where the Eiffel Tower didn't spoil his view.
