I think that the soups at Surdyk's are very tasty, they make a walleye chowder there that is so good, my mouth is watering at the thought of it. They don't always have it-the selection changes often. However, when I don't feel well, toam yaam with chicken from Chaing Mai Thai (convenient place for me to get take out) with 4 flames of spice really does the job.
Cafe Latte consistently has really great soups - the selection changes frequently, but there's usually something cream-based (does that count as chowder then, or is chowder something more specific?).
In an effort to be more specific (for Enso): good quality ingredients, well-balanced flavors, not too salty, generously chunky (when appropriate), not too salty. It's hard to be more specific when the options vary so much and time is limited!

I know others will have much better answers, but the two places that pop into my head are Lunds and Quang.
Lunds has really good soup to go. I especially like their signature wild rice soup and the chicken noodle soup.
Quang is ultimate soup place for me. All the soups are good, but I especially like the vegetarian one, though I'm not a vegetarian. It is just a little lighter than the rest and very tasty. The pho, of course, is the go to and very good. Or you could stop at Pho Tau Bay if that is more your speed, or one of the St. Paul pho joints.
And I don't know where to get chowder, sorry.
