If you're looking for a quick, wholesome lunch, I must recomment the Panera Bread restaurant.
They have a lunch special called the "You pick two" - a soup, a salad or sandwich. At at only $5.99, it realky fills you up!
My favorites are the French Onion or the Low Fat Chicken Noodle Soup - and always the Sierra Turkey Sandwich. I don't know what it is about the sammie - the asiago cheese bread, the spicy mayo or the real turkey breast - but it is my absolute fave there.
They also have great bagels and desserts too! I say - check them out!
