I'd have to go, in general, with The Palm, but only certain locations. Dallas, DC (downtown, not Tysons) and Denver. Of the three, DC is certainly the best of the bunch, owing to the extremely long tenure of the manager, who is probably more powerful in Washington than some Democrats these days.

The Chicago Palm at the Swissotel isn't bad, either, but there's so much good food in Chicago that it's hard to say anything is really all that bad.
I've tried a lot of the Texas steakhouses in Dallas--III Forks, etc.--but the quality is lacking in the beef, IMHO. Plus, there's Papacito's there and it's hard to get anything but a tortilla chip and salsa in/on my hand in Dallas.
I've done a lot of the Ruth's Chris, the Morton's, etc.... but all of the chains have quality control problems at this point due to scale. Then again, it's the little differences that make these chains good--the blackened ribeye at The Palm in Denver is unique for some reason.
