I've dined at Yachtsman, Shula's, Concourse, Le Cellier, which are the primary "steakhouses" at WDW. I've also had steak at Artist's Point, Citrico's, California Grill, Jiko, Fulton's, and Bistro.
Of all of them, a Texan steak lover would probably most enjoy Shula's. It's also probably the most expensive.
I prefer the filet at Jiko over all of them, phenomenal! But it's not a slab o' meat on a plate, which it sounds like what you're looking for.
The Concourse is OK, but it's a "B" level steahouse--much better than Sizzler, but not outstanding by any means.
Le Cellier is another good place, although we had bad food and service there last year and haven't been back. We think that was a fluke, but it's perhaps one of the more inconsistent of the list.
Had a TERRIBLE meal at Artists Point with a steak that was worthy of being called shoe leather. Ate there agin a few months ago, had a much better meal but steered clear of the steak.
Citrico's and Bistro have great steaks, as does Fulton's, but none of them are steakhouses, and I do'nt think what you're looking for.
Yachtsman's--After suffering through a bad slump for a few years, they're coming back strong. We've had some good meals there lately, and it would certainly be a worthy choice if Shula's isn't going to work for you. Depending on teh appetites of your party, it could end up being a less expensive option.
Just my thoughts...
