Any practical nearby alternatives to Galatoire for Friday lunch?

Next month I am in town for a convention. On Friday I have to speak at one session until noon at the Hotel Monteleone and then chair another at 2:30 in the Sheraton. I am hoping to organize a lunch for 4 during that interval.

I gather that Galatoire although conveniently located to both is not practical for a Friday lunch on such a tight schedule since it takes no reservations(??) for that particular meal. Is my assumption correct?

Are there any attractive practical alternatives in that neighborhood? I don't require a resto as high end. And in fact cheaper would probably be better. What I seek is something where four can eat something distinctively NOLA and good for lunch and get in and out in about 90 minutes.

That evening some of the lunch party will be dining at August so we probably don't want to bust our budget and our guts twice in the same day.
