I have yet to find an excellent chicken fried steak at a restaurant.
The best I have had lately, was at Toby Keith's for $17, too expensive, but you don't leave hungry.
Texas Roadhouse, surprisingly, has a decent CFS. I'm not going to say it's powerful enough to make the world stop spinning, but I was impressed something that tasty came from a chain restaurant. It's a bit salty, though, but a few bucks less than $17. I've had Toby Keith's CFS and I'd rank Texas Roadhouse above it.
Try the CFS in the Skillet Restaurants found in random truck stops (I-40 and MLK/Reno in OKC, for example). It's rated by truckers as the #1 CFS. I figured if truckers, people always on the road looking for something to remind them of home, like it, then it's worth a shot. It's really not bad, actually. It's a toss-up between Skillet and Texas Roadhouse for my favorite CFS.
Chuck House claims they have the world's best CFS. I'd agree, they do have the best CFS... for the price. It's like $6 gets you a CFS, 2-3 sides, and a drink. Can't beat that deal, but standing the CFS against the others, it's nothing special.
