Clarifications & disagreements:
Do both Fairview and Highland turn into Main, there being a profusion of Main Streets in that neighborhood? My bad on Finley/Belmont, and thanks for the correction.
L'Anne is really a Vietnamese-influenced French restaurant trying to be more mainstream American to pump its business up. It started out somewhat interesting but no one was buying, so they have gradually moved more and more mainstream which picked up business but convinced me never to go back - expensive and boring for me these days.
Adelle's is bistro food? Maybe bistro means casual but ambitious dining 'cause it also seemed more American with some French & southern-cooking influences. But I admit to only dining there once. Probably better than L'Anne at this time, but not terribly exciting.
Les Deux Autres is expensive and has its charm, but I would never choose it ahead of Vie - they really are not even in the same class, as much as I want to like and support LDA.
Mykha's is more interesting, and really is slightly upscale Vietnamese (as opposed to L'Anne where the Vietnamese is usually restriceted to a couple of dishes and one or two accents). One can get a pretty good meal there. My one issue with it is that she pretty much uses the same set of seasonings (lemon grass, touch of garlic, etc.) on every dish, so it gets a bit boring. Not a problem for the first or second visit, though.
Luong Loi in downtown Wheaton is decent, not wonderful but decent, Vietnamese. Fairly authentic, though they do slip some Cantonese dishes in there, and quite cheap.
The Indian places mentioned above are also fairly enjoyable, not too expensive and quite authentic.
All of the nearby towns have charming little downtown areas, usually around the train station, that can provide a pleasant walk. Wheaton and Glen Ellyn are a bit nicer than Lombard, Westmont and Downers Grove, though Westmont offsets all that with the best selection of places to eat though those are mostly not downtown. Downers Grove has the benefit of the Tivoli Theater, which is quite nice - most of the towns have interesting old theaters, but the Tivoli is the only one in really good shape.
Naperville combines a selection of restaurants, some of which are even pretty good, with the river and river walk, plus it is by far the busiest so you get some people-watching in the bargain.
If you come back Tasty Boy, think of all the options you will have. Hey guys, maybe we should do a Tourist's Guide to the western burbs with all this info.
I was waiting for Flip to weigh in since I know he works right there (see, I got it right

) and thus is an expert in convenient and good places to dine in the neighborhood. But I see he limited himself to geographic clarification. Smart guy.
