I haven't ever had the gumbo you are talking about, but I do know that I had a wonderful seafood gumbo at Boma one night. I make a lot of gumbo at home, from duck, to crawfish, and everything in between. I thought it was excellent. The recipe was available on AllEars and I have even made it at home and got excellent reviews. I hope you find somewhere that has something similar! If you do, please let us know. It sounds really wonderful!!
