There's always Sunporch on University. My very very favorite restaurant ever was upstairs Sunprint on State -- bye-bye now.
(I'll finally edit instead of posting AGAIN...)
If you can't tell, I'm kind of taking a mental walk along State St. It's nice. I'm so thrilled about going back. I haven't been there once since I moved 6 years ago, and not at all since I moved here (Chi-town), even though a specific selling point was proximity to Madison.
Here's the motherlode (from Swimp's link):

PASQUAL's is what I was trying to remember, the SW place. Pretty good!
I think Bluephies is the best bet so far for food + space.
