The Ranch, then Mahogany. I have yet to eat at Signature Grill, but I have not heard one bad review of the place. MIckey Mantles used to be pretty good, but the last few times I have eaten there it hasn't been as good.
I think some of the best steaks aren't served at "steak houses" The Metro, Paseo Grill, Coach House, Rococo just to name a few have pretty good steaks.
10oz filet medium rare with a side of green chile mac and cheese and asparagus, followed by either a crème brule or a brandy ice, all accompanied by a bottle of Pappion or Cakebread and you're good to go...
