2. Grab a Coffee at Café Du Monde
The most famous café in New Orleans is incredibly popular but also incredibly busy. If you can fight your way to a seat with your cup of coffee (the chicory blend for which it is famous is an acquired taste), you can easily while away an hour or two people watching. If not, grab a takeout (the line is shorter and moves quicker) and walk the short distance to Jackson Square to cop a squat.
