Perini's for sure. It's hard to beat Tom's steak, green chile hominy, cowboy potatoes, Zuchini Perini, sourdough bread, strawberry shortcake, and bread pudding.
Joe Allen's is a classic, and I ate an outstanding steak of his at the Texas Cowboy Reunion here in Stamford on Tuesday, but I've heard that his new restaurant is mediocre compared to the old shack.
His ex-wife, on the other hand, is going strong with Lytle Land & Cattle, which, outside of Perini's, is the best steak in the Abilene area. She also just opened up Sharon Allen's Barbecue & Catering, which was outstanding the other day when I was in there at lunch. It was as good, if not perhaps actually better than Joe's back in its heyday.
