There are several sure signs of a great greasy spoon: Pickup trucks outnumber SUVs, "Texas toast" is a staple food, you feel the need to check your fork for stray remnants; and you leave feeling guilty yet satisfied. The Pig Stand easily meets all the criteria. Piggy No. 7 (yes, others do exist, just not in Houston) opened in 1921. Since then it has served up chicken-fried steak, liver and onions, and Pig Sandwich combos to all walks of life, be they lawyers, Sixth Ward bohemians or visiting executives escaping downtown for a dirty pleasure. Should the restaurant's name ever escape you while slurping a perfectly made chocolate malt, you can simply look around at the numerous pig pictures, figurines and collectibles. Homegrown kitsch is another solid indicator of a true greasy spoon.
