Laura, here are some hints in New Orleans:
Go to Cafe Du Monde early ( around 730-8am). It is a great breakfast spot and usually no crowds at that time.
Go to Laffeyettes "Pirate Bar". Oldest tavern in U S.
U don't have to wait in line for a muffellatta at Central Grocery, pretty much every deli in the Quarter has them and they are good.
Have fun. Vtd
