Hi- I have a sister that lives in New Orleans, and I have been down there many times for jazzfest. One place that is cheap and is near downtown is Meals from the Heart at 1100 N. Peters. They have wonderful crab cakes, and their crab cakes are usually voted the best crab cakes by readers of Gambit magazine. They are located right down the street from Cafe Du monde, which he should also check out, and across the street from Margaritaville. They are self serve though. Central grocery has wonderful muffilatas. Acme Oyster is located in the Quarter, and is not expensive. They have really good fried oysters. Mothers is loved by the locals, but my sister and I checked it out, and decided not to eat there, because it is a greasy spoon, and neither one of us cares for greasy spoon places. Your husband would probably love it though. My sister is a doctor down there at LSU, who specializes in diabetes and lipid disorders, and she says that diabetes and heart disease is rampant in the city.
There are lots of posts here about places to eat in New Orleans. Is he staying near the convention center? I know that this is nowhere near the convention center, but there is a new donut shop/coffee place on Magazine, just a few blocks from my sisters. It is called District Donuts Slider Brews. It is located at 2209 Magazine. I did have a cup of coffee last time I was there. My sister quit drinking coffee, and I needed a caffeine fix the last time I was there. There coffee was expensive, but was okay. I like Community Coffee down the street better, and it is cheaper. This place had donuts that were to die for though. The donuts were $3 a piece. I was tempted to buy one, but I passed because I was scheduled to have a cardiac catherization when I got back home, and I decided I did not need the donuts. At least I know now that my arteries are clean as a whistle, and so I went through that for nothing. Hope this helps, Nancy
