Some encouraging posts earlier in Chowhound neglected one significant fact. A lot of places down LA1 to the barrier Grand Isle are closed in January and definitely closed Sunday. So a trip Sat-Sun in January was intensely frustrating. Highlights: Good oysters at Big Al's Seafood in Houma. Early boiled crawfish were tasty enough but not seasoned fully (to my taste). The only place open down towards Grand Isle was the Cigar's Marina place. This was OK but of the three occupied tables we were all obviously tourists and no locals action at all. The food there (especially gumbo) was good however. Interestingly the one thing impossible (at least Sat-Sun in January) to obtain on the road to Grand Isle are raw oysters in a restaurant at least(!)
Other highlight: the pecan-praline-eclair donut (don't knock it till you try it: not overly sweet) from Rob's 24-hour donut shop in Houma.
Also the tunnel under the Intracoastal waterway in Houma. An unusual & unexpected bit of civil engineering.
Sorry no better stuff to report. Needless to say the legendary Bourgeois' Meat Market in Thibodaux *CLOSED* Sunday. Cracklin' & jerky shortfall to add insult to injury: I asked a local man and he could not recommend ANY hot cracklin' place open Sunday (to me fresh-cooked cracklin's taste so good on a Sunday morning). Wish the original poster had mentioned that the "Road to Grand Isle" is not a 12-month Hope-Crosby movie by any means. I imagined even in cold-weather months (especially with oysters & crawfish in good season) would be prime time to visit.
Since I made the trip from Oklahoma based on posts here can I urge folks to mention significant seasonal facts please(!!!)Disappointed.
