Harry Heftman of Harry's Hot Dogs, 300 W. Randolph, turns 100 Sunday. His hot dog stand, which he has run since 1954, closes in April. A skyscraper is moving in.

What to do? Have a birthday party, of course. Da Mare is supposed to show up at 11:30 a.m. today to fete Harry with a cake decorated as a hot dog.

Our inimitable Neil Steinberg knows and loves Harry. He's written about him at least 15 times in the last eight years, including today. Steinberg will be there today, and he'll take ketchup on his dog, he says. Don't get all worked up -- Harry once told Steinberg ketchup is OK.

"Enjoy life," Harry said.
