Fronterra and Topolobampo aren't
that far from there, and I think Naha and NoMi serve lunch, too. Bin 36 is also close by, and I've always found them to be reliable if not surprising. Keefer's, too, has a cafe open for lunch.
Pricing it a bit lower, I'm always happy to eat at Big Bowl, off Ohio. I think they've tried to hit the organic/local vibe recently, and their pad see ew with tofu and spinach is remarkably tasty.
I've also heard passable things about the cafe in Nordstrom's (the restaurant in the actual store, rather than what you'll find in the food court on the same level -- that being said, though, that food court is decent, as is the food court in the mall with Saks, further up Michigan). Also, let's not forget Hannah's Bretzel in the Illinois Center, or even Pastoral, off Lake, if you're in the mood for a great sandwhich.
