I chose to eat at Homeside restaurant, on Old Huntsville Rd, last Friday when they had all you can eat Catfish, or that's what was stated. I did ask where the catfish was from and what was revealed was that the whole catfish was from a Mississippi Catfish farm but it was the boneless filets that I was interested in and was sorry to hear that it was an Asian fish from Vietnam or Thailand. It was truly boneless and was said to be "like catfish" and for someone that didn't know they might very well believe it was catfish if they didn't ask.
As for me maybe I shouldn't have ask because, maybe it was set in my mind, it just didn't taste right to me and certainly didn't taste like the catfish filets I get at Swamp John's and at Newburns. It wasn't near as good. Homeside usually has a lot of business but at least know that if you go and order boneless that you are getting something other than USA Catfish.
Now regarding catfish, specifically filets, I have found that not only does Swamp Johns give you the best value for your money (barring any all you can eat places or offers) and also is some of the best tasting. Newburns is very good catfish and you can get filets and whole catfish, which you cannot do at Swamp Johns, but Newburns will cost you quite a bit more for what you get also.
There are lots of places around the Shoals where you can get catfish but only one can I say was completely inedible and horrible and that came from Cracker Barrel. I like Cracker Barrel's Cod Fish that is a Friday Special but I can honestly say, for my part and opinion, Cracker Barrel served me the worst catfish, by far, of any place I've ever ordered catfish at.
