I think you named most of my current favorites.
One soup I love is split pea but I no longer have a go-to place for it, so if anyone can recommend a good one, I'd really appreciate it. I usually end up making it myself.
Prairie Grass Cafe in Northbrook makes some very tasty soups but they only have one per day and I'm not sure if they're scheduled or not. Another soup I love is the revithia soupa (chickpea soup) at Avli Estiatorio in Winnetka. Again, I'm not sure if that's always on or not. I really enjoy the laghman at Chaihanna in Buffalo Grove, too and I'm fairly certain that's always on the menu (they have many soups there but the laghman is my favorite).
