I'm trying to help an author with a book party in July. He's a very city guy
and was thinking about (dirty) dogs, which his character eats regularly.

I just found this online:

olk-party-rentals-johns-hot-dog-carts-long-island-li-ny/27172589

But . . . any other ideas? I was actually thinking about the dog equivalent
of sliders, i.e., cocktail-sized. Would or could anyone --- a creative
caterer you might recommend --- do this?
