My wife and I ( from Columbia, SC ) will be spending 3 nights at the Maison Dupuy Hotel in September. My wife is gluten intolerant ( allergic to wheat/flour products ). I would assume any dishes made with a roux would be off limits for her. Does gumbo contain flour as a thickening agent? Are there restaurants in the Quarter that offer glutten free menus? Any restaurant suggestions and local dish recommendations within walking distance of the Quarter would be greatly appreciated.
