You are on your own for dinner this evening (Sunday). See the bottom of the conference location page for links to nearby options. Or, if you just want to wander, see the online map for restaurant-enriched neighborhoods. Fourth street from Indiana Avenue to Walnut St. and Fifth Street (Kirkwood Avenue) from Indiana Avenue to Rogers St. both have an array of amazing options. The square downtown is a great find as well.
Find someone you don't know, share a meal, and learn what others are up to.
