It can be tough to find a quick, low fat lunch but Zoup seems to make an effort to have at least one low fat and vegetarian choice available among their 12 "soups of the day". You can order ahead by phone, fax or email but for the most part the system of ordering at the counter moves things along quickly. I have to disagree with another reviewer, they have several salad choices and there are a couple of sandwiches that lure me away from my favorite soups. Servers are friendly and patient with sampling. They have accommodated my requests for layering 2 types of soup (vegan black bean with Mac and cheese!) cheerfully and even make suggestions of their favorites. Some soups seem salty and although they offer nutritional information on other aspects of their soups they do NOT readily have sodium counts available. Would like to see this in the future. A little pricey for lunch but it is a step above "fast food".
