LeDoux is a Cajun restaraunt north of Troy, Ohio in an odd location--they have a corner of what I think is a medical office building near the hospital. Decor is OK but looks like it was ordered from a Restaurant Decor catalog.
I've eaten at LeDoux twice. The first time was very good--I don't remember what my dish was called but it was some sort of pork with a spicy sauce over rice, and a cup of gumbo as a side. That meal was good enough that when my Dad offered to take me out for lunch, I opted for Ledoux again instead of my favorite, La Fiesta.
Unfortunately this time wasn't good. I can't entirely blame them for the Swamp Trash appetizer--it had Alligator and Crawfish, and since I've never had either one it may be that I just don't like them. However I had a main dish of Jambalaya with chicken and sausage. The sausage was OK, but all of the chicken had an off flavor that reminded me of chicken skin accidentally left in homemade soup. All my dishes had a flavor of old fry grease that needs to be changed, including the dirty rice side dish. I had half a Boudin Ball from someone else's appetizer--Much better than my dishes, but didn't have enough to judge thoroughly.
LeDoux may be authentic, I wouldn't know. I prefer Zatarains mixes from the grocery.
