We are going to be in Tulsa for a few nights this week, staying downtown, and working fairly late. Where could we sit down after 9 pm for a relaxed, not-too heavy and interesting meal? We frequently just eat off the appetizer menu , don't want to eat food that is too rich, and are more interested in interesting and authentic approaches than food that tries too hard to impress. We all come from different cities, so there is nothing in particular that is too much like food from home. Any thoughts, hounds?
