If you can't handle crowds of people, this isn't the place for you. However, if you enjoy digging (and then haggling) for that perfect bargain, you might be in the right place.
The French Market is divided into a covered market section and a community flea market. The community flea market often has some interesting local vendors, while the covered market seems a little more commercial in some parts. Many vendors sell the hot sauces and hurricane mix you can find all over the city, but some are selling local plants and vegetables or unusual jewelery. The snow cones and lemonade often for sale here are both tasty ways to beat the heat.
Overall, this place really is a treasure hunt, so if you aren't prepared to spend some time wading through the junk for a real bargain or two, you may want to skip this attraction.
