I'd recommend Continental if you are looking for a quick, and light bite to eat. The salads are quite good (especially the spinach one) and come with lots of cheese, which is good if you like cheese. The lentil soup and the chicken soup are also both good so pick whichever one you prefer.
Continental also sells foods for cooking at home, such as feta cheese (both imported and domestic) and phyllo dough. The lady that works the front desk and serves on the north side is really friendly and personable.
