What is it about a bowl of piping-hot red that enables it to create a culture all its own? Chili cook-offs, chili championships, chili parlors, chili with beans or without. What's the best chili, the hottest, the reddest, the meanest? Texas chauvinism aside, none of these is an easy question, and weighing into the great chili debate about what constitutes the best chili can be just plain foolish. But here goes, anyway. The chili served at Highland Park Pharmacy for at least the past 20 years, and probably longer, is our sentimental favorite. No, it's not hot; no, it's not spicy; and yes, it's full of beans. But it's mighty tasty, goes down smooth and is a welcome complement to just about any sandwich the old-fashioned soda fountain has to offer. Summer or winter, it just seems to work its magic, particularly when doused with a chocolate malt or a vanilla Coke.
