I haven't eaten at this particular Steak 'n Shake but I have at others when I used to live in the Dallas area. Fine cuisine? Don't expect it - just simple comfort food. The five-way chili (better known as Cincinnati style) is excellent, and the burgers - ahem - steakburgers do not disappoint.
Only drawback I've seen from reading other Yelp reviews is that there's only one location and it tends to get crowded on weekends.
