We live nearby Chicago on a Bun and would drop in there every once and a while for a hot dog fix. A month or so ago we discovered they are under new ownership and it's very noticable when it comes to the chow. On our most recent visit over the weekend, the place was busier than I have ever seen it, I guess word is getting out!
Hubby and I each had a spicy dog on a fresh poppyseed bun prepared Chicago style. It was topped with tomatoes, onions, mustard, relish, mini hot peppers, a crisp quarter spear of dill pickle, and I added shredded cheddar cheese to mine. The dog was plump and juicy with a tasty bun that held up wonderfully under all the toppings. The casing made the pleasing little snap that comes when you take a bite out of a great hot dog. The shoestring fries are delicious and abundant. While the price for the fries is a little steep ($2.75 I think?) it can be shared between 2 or 3 people.
They now have ribs and I overheard one of the new owners telling another customer that they have redone their burger. I'm so obsessed with their spicy dogs that I don't know if I can bring myself to try their other offerings, but I was salivating looking at everyone elses plates.
I highly recommend any local hot dog lovers make their way over to the new and improved Chicago on a Bun, you won't regret the trip!
