go to the camellia grill at the top of st charles and get some pecan pie at the end of your meal. go to cafe du monde and eat like 3 orders of beignets. get some crawfish at some point. go to domellici's and get a po' boy - i like shrimp. gotta get a muffelatta from central grocery too - that one is great for your last day there too, goes on the plane and travels great.
don't go there for snowboarding. go there for food.
