Ours is 7 1/2 now, so it's been a while since I was mentally tracking all the best places for infants. At the time, we lived on Argyle and we found that Asian and Indian restaurants seem to be almost universally baby friendly. So I'd say add virtually all of Argyle and Devon Ave. to your list. Ditto almost all Mexican restaurants that I've been to.
Also in Uptown,
Tweet Let's Eat on Sheridan was very friendly to us both at weekend breakfast and dinner. Tables are somewhat closely spaced, but it's a generally noisy, boistrous atmosphere and we never felt we were stepping all over someones intimate romantic dinner.
We had a very nice grown up meal at
Deleece with kids in tow and felt both welcomed and, even as the room filled up, didn't feel that the neighborhood clientele wished we were elsewhere.
And of course all the major Chicago pizza institutions are very family friendly. Including the newer stars like Spacca and Sapori di Napoli (although the latter's room is fairly small, so you'll have to judge how well the temperament of you angel suits the room).
Toast in Lincoln Park was also very accepting of our young 'un, and, I believe, even sports a kids' menu.
In Lincoln Sq.
Fiddlehead Cafe seemed happy to accomodate us both at brunch and at dinner.
That's my top-of-mind list at the moment. Not very local for you, but hope it helps somewhat.
