3.5 stars.
This is one of my lunch mainstays. People at the office make fun of the fact I eat here seemingly every day. (But really no more than three days a week.) To be honest, however, I come here because it's not greasy or rabbit food like 99% of the other options in the PATH, and doesn't feel too unhealthy as long as you stay away from the heavy cream-based options.
Most of the soups aren't great. They use too much cream in the cream soups, and too much oil or thickening agents in the other ones. The chilis are disappointingly bland with frequently undercooked ingredients. I stick to the Jamaican Crab Bisque (great flavour but a little light on the crab), Italian Wedding Soup, Aztec Chipotle Chowder and Senegalese Peanut Chicken.
This is a good option for the PATH but if you don't work downtown you're better off walking a few blocks west to Ravi Soups.
