Enough about science and talks, lets discuss food options. One of the food places I've frequented the past two days was Rice Paper (on Central and Monroe) for lunch, and the experience has been pretty good. It is Vietnamese Cuisine and has both restaurant area, a patio, and a small bar. Their menu ranges from Vietnamese sandwiches (banh mi), salads, pho noodles soups, and entrees (but they aren't available until after 4pm). Their service is pretty speedy and the food doesn't take too long to deliver to the table...which is perfect if you are in a rush to go back to the convention center to catch the next talk!
