The somewhat legendary 2 a.m. must-have, the Seattle Dog, got its start in Pioneer Square, but it has been perfected on Capitol Hill. It comprises a grilled bun slathered with cream cheese and topped with grilled onions. In 1988, bagel man Hadley Longe tried selling bagels to club patrons in Pioneer Square. But who wants a bagel at 2 a.m.? He started putting hot dogs on cream-cheese bialys, and a new trend was born. Other vendors eventually replaced the bialy with the bun, transforming the hot dog into what it is today. My favorite vendor is the hot-dog stand by Chop Suey. Stepping up to the grill (and under the tent, if it’s raining) feels like slipping into a pool of calm, worlds away from the hooting, drunken frenzy of a late night on the Hill. Vegetarians, choose a perfectly grilled (read: not overcooked and rubbery) smoked apple sage for your Seattle Dog; the sweetness of the apples are offset by chunks of Yukon Gold potatoes and a subtle smokiness.
