I visit Soup Nutsy occasionally, when I am in the mood for a hearty, satisfying soup. Their menu changes daily and you can find the daily specials on their website which is very convenient.
They have a soup and a sandwich special, but I always just get a medium size soup which comes with two sides (veggie sticks, fruit or bread) and it's a perfect lunch portion. The cost comes to $9.15 including tax which really isn't bad.
If you have food allergies, their website clearly details which soups are dairy free, gluten free or vegan which is a very nice touch.
