Finally saw their truck at The Willo Home Tour event. And I was hungry so I got two dogs: a regular wiener with coleslaw, Swiss and thousand island dressing. The other was called the "Bear" and seemed to be named a "7th inning stretch favorite" since it included peanut butter, Cracker Jacks and nuts. both very good but would've been better with melted cheese. The warm flatbread is a great touch and allows more toppings to surround the dog.
Service was friendly and efficient. I'll be keeping them on a short leash in the future...and look forward to trying more of their concoctions!
