Have not been to orleans, but Brothers In dorchester is serving up some of the best crawfish north of the maison dixon. There asian fusion flavor is most similar to new orleans style boil. Sometimes closed on mondays if they run out over the weekend.
Owners name is listed as Trang Tran-le; and yelp reviews have been favorable. I'm thinking I might try it, but probably not until I try Brothers Crawfish in Dorchester. I agree spamming the board is not cool!
