Carsons on Peterson and Clark is indeed closed.
Past faves of mind from that part of the Chicago area:
Dave's Italian Kitchen (Chicago Ave just south of Church in Evanston)
Daruma on Central in Evanston (although it's just not as good as it used to be, I think)
Renga-Tei at Touhy and Crawford in Lincolnwood
What is patriotism, but the love of good things we ate in our childhood?
