There's no view, but
Le Titi de Paris is the best (and fanciest) French restaurant in the northwest suburbs. It's still open, slated to close next month.

Two other French places in the northwest 'burbs are
Barrington Country Bistro and
D&J Bistro. Both are quite good, but a step down from Le Titi IMHO.
I'm not sure you need to rule out going downtown just because of the NATO summit.
Everest is the obvious choice there, between the French cuisine and the view from the top of the Midwest Stock Exchange building, looking out over the city. It might be worth giving them a call to ask about how much hassle it would be to get there.
One other possibility is
North Pond, where Chef Bruce Sherman just won the James Beard Award for best chef in our region. It's three miles north of the Loop, so there's no concern about the NATO summit. And the view is fantastic; it's in the middle of Lincoln Park (the park itself) facing its namesake pond, and if you're in the front room, the full-length windows face its namesake pond with the city skyline looming over the opposite shore.
