I missed the part about the 12-year-old. Not only does that rule out most barroom/nightclubs, it might impose an earlier curfew than would otherwise be in effect, considering your very early Saturday wake-up call.

I'm not sure; it's a long time since I had a 12-year-old. I know that teenagers can generally get by with less sleep than adults, but I'm not sure of the age at which they begin developing nightowl tendencies.

There will be precious little daylight during your brief visit. Unless I can pick you up at the depot, and then make a half-hour-or-so detour before dropping you at the hotel, we won't have much opportunity for the "disaster tour." Well, I suppose there's a little time available Saturday morning between sunrise and your train's departure, but I certainly don't plan on being awake that early...

Live Cajun music during dinner at Mulate's is certainly an attractive option. After dinner, Friday-night options might well be limited by the youngest member of the group, but any venue that serves food as well as drink may legally admit minors. The famous Mid-City Lanes Rock 'n' Bowl (live music at a bowling alley) might be a best-bet, depending upon who's on the bill.
