Where can I buy a bottle for under $20 in New Orleans?
Are you having trouble finding it at all, or just under $20? They definitely have at least two or three brands at Rouses, Dorignacs, and Vieux Carré Wine & Spirits, but I don't remember the prices. I would be surprised if Martin's on Vets didn't have some, though I've never bought it there myself.
Vincent's on St. Charles makes their own - not sure if they sell it by the bottle or how much. You could give them a call.
