I collected some friends from work and finally made the pilgrimage to Speed's today. Both Speed himself and his apprentice/heir were at work today. We had a nice chat with both of them (there was no line), and we all ordered ours with everything.
Phwoah! We four agreed that these were the best hot dogs we'd ever had in our lives. Plenty of love and craft go into their making, and an eye-popping array of mostly homemade condiments (Words to another patron: "It's not ketchup, it's our own sauce, but if you like ketchup, you'll like this.") It's really an experience, even eaten standing around in the dust and diesel fumes of Newmarket. The dog itself is massive, by the way.
I know I'll be going back soon. They promised to add Tuesdays very soon to the current Wednesday to Friday schedule (11am to 2 or 3pm in good weather), and add Mondays after Memorial Day.
