My girlfriend and I (mid-thirties)are travelling to N.O. mid-September. We want to eat, drink and hangout where the locals eat, drink and hangout. We love creole food, jazz and blues. What are the can't miss places? Also, we want to have one break the bank, fabulous dinner - I've been told Peristyle, New Orleans Grill, NOLA. Suggestions? Thanks for your help.
