Founded in 2011, Hot Diggity Dogs is keeping it simple. The Seattle-based cart is steamin’ up the good stuff, serving an array of different dogs, sausages, and toppings. What’s your tube-shaped meat of choice? Polish? Chicken apple? Kielbasa? Brat? They’re also carrying 10 different mustards and some carefully selected toppings, so whatever it is you’re craving, Hot Diggity’s got you covered. Track ‘em down in the Seattle Metro area or book ‘em to cater your next event. MUST TRY Fireball — 1/4 lb hot link with horseradish sauce and pepperoncinis on a hoagie roll
