There's a small establishment on Lovers Lane, just off the North Tollway, in Dallas called Goff's. It's the last one left of a former chain run by Harvey Gough. He has a rather unique sense of humor, placing a statue of Lenin out front. If you don't mind a little good natured verbal abuse, you might find Goff's rather interesting. (Everyone is equally subject to his barrages.) One example: a person went up to the counter and he asked, "What'll it be, Beast?" And there were instances of customers ordering a Coke or a shake, and being asked if they wanted it in a sack. If the answer was "yes" there were times when he would pour the beverage into the sack.
A lot of people wonder how he's stayed in business all these years. I guess it's because the food is pretty good. It's worth a look see.
