Anyone know the recipe for Urth Caffe's Corn Chowder?

Help! Does anyone have the recipe, or a knockoff or copycat recipe, for the Corn Chowder at Urth Caffe?

I have vegetarian houseguests coming and that Corn Chowder is one of the best things I've ever eaten, vegetarian or otherwise. (Its actually more of a broth soup than a creamy chowder.)

Any ideas?
