The short answer
There is no correct number. For a three- or four-day trip, several well-chosen dishes across different meals can provide more understanding than forcing gumbo, jambalaya, red beans, a po-boy, muffuletta, oysters, beignets, and dessert into every available hour.
Use variety intelligently
Balance soups or stews, sandwiches, seafood, rice dishes, sweets, and lighter meals. Share when portion size permits. Try multiple versions of one dish only if comparison is part of the interest.
Do not confuse popularity with obligation
A famous dish may be too rich, spicy, messy, or unsuitable for a dietary restriction. Choosing something else is not failing at New Orleans. The point is to enjoy and understand the food, not complete an assignment.
Ask better questions
Ask what the restaurant is known for, what is seasonal, what is prepared particularly well that day, and which dishes are difficult to find elsewhere. Those questions often produce a better meal than ordering only by fame.
