When we stopped into Frankfurter Express last weekend, reader Frankvw suggested that we give A Chicago Street Grill, the replacement for the diner that used to be set-up in Big's on Potranco a shot. We did just that, and I'm here to do a quick report!
First, I have to be very clear. You can't do a head to head comparison between Frankfurter Express and A Chicago Street Grill. These are two totally different venues with two different customer sets. The only thing in common is that they both serve quality dogs.

A Chicago Street Grill offers a huge selection of not only hot dogs, but burgers, Gyro's, meatball sammaches and more. If you ignore the convenience store behind you, you can sit back and appreciate the Chicago memorabilia adorning the walls, and pretend you are getting ready to watch Da'Bears.
My wife ordered a Windy City Chili Cheese Dog. These are regular sized dogs served on a fresh bun and, your order includes free fries that are cooked fresh and lightly seasoned.
I ordered up The Chicago Hot dog which is served on a poppy seed bun, kosher dill pickle spear, tomatoes (I had never experienced tomatoes on a hot dog before - not bad), sport peppers (which I took off and ate separately) and chopped onions. It usually comes with relish, but they were out. No biggie.

The owners of the place seemed genuinely friendly and eager to make us happy. They made the food quickly and everything was good. I'd be eager to return just to try out some other items on the menu like the burgers, the cheese steak or some of the fried appetizers like mushrooms, onion rings and jalapeno poppers.
If you just need a quick hot dog fix, I think you'll be fairly pleased with the prices, especially considering the fries come with the dogs. Have you tried some of the other stuff there? I'd love to know what was good and what wasn't. Tell me about it or leave a comment below.
