Stormy's (formerly Seul's) in Northfield seems to carryover the pretty good daily soups of their predecessor. Haven't had one at either incarnation that I was disappointed with. I've liked the soups from Eat A Pita by Halsted and Belmont for years. Always part of any meal I get from there. They feature one cream-based and on broth-based soup each day. The Split Pea and Clam Chowder are my favorites.
