Here's the Chicago dog from Phat Burger Bro. It lacked sport peppers (and of course, poppy seeds are unavailable here) but it was otherwise edible enough.

The burger was quite nice, with a coarse ground meat patty, slightly smoky, tasty and layered. A very fresh tasting burger, with nice layers of flavours with the light sauce, cheese, pickles and slightly caramelised onions. I would have liked it more meaty and smoky, but this was not bad.
