Definitely bring her through Elmhurst. Specifically, bring her through these particular areas. While these areas might border each other, each has a different feel in my opinion. I live on Grosvenor, which is close to Chalkstone and more similar to your neighborhood. These other areas are quieter, less diverse (or at least lack the "cultures" that like their streets littered and their music loud enough to hear 3 blocks away).
The area surrounded by Smith St to the north (or even Wabun or Whitford to the north), River Ave to the east, Academy Ave to the west, and Pleasant Valley Pkwy to the south. This is my favorite area of Elmhurst. We almost bought a house here, but it was too much house for us and just out of our price range (we were looking for a purchase price of no more than $200k).
The area surrounded by Eaton St to the north, Hilltop Ave to the east, River Ave to the west, and Smith St to the south. This is close to PC, but very few, if any, students actually live in that area.
The area surrounded by Admiral St and Isabella Ave to the north, River Ave to the East, Gentian and Smith to the west, and Eaton St to the south. I used to live in this area on Sharon St.
All of Gentian is also pretty nice until the very end near Admiral St. The area between Smith St and Mount Pleasant Ave south of where they intersect and north of LaSalle Academy is also nice, but with few walkable amenities. The area between Mount Pleasant Ave and Academy Ave just south of LaSalle is, again nice, but not quite as nice as the 3 areas I mentioned above. In those 3 areas, you'll find lots of young families on those areas. I don't know of you guys use RIPTA at all, but the beauty of Elmhurst is the peace and quiet and the close proximity to the bus routes in pretty much the whole neighborhood. It's a great neighborhood for people who want the amenities of the city but the quiet and roominess of the suburbs (though it's not as roomy as going to the outer suburbs).
