Let me start with the caveat that I haven’t been there since the mid-90s. But, there’s an establishment in Houston, the Taste of Texas, that had some of the best steaks I’d ever had. You used to be able to pick out the steak you wished at the display case when you entered, they had an excellent wine selection and they do have a Tomahawk steak on their menu. The price listed is $116 and it’s 38 oz.
Might be worth a shot.
EDIT: Just checked and Houston is way, way farther from DFW. Sorry about that.
