I came here 1-2 times a week for a semester. Probably not the healthiest option, but it was one of the most delicious!
Always go for the special of the day as it comes with the dog of the day, fresh fries (or potato salad), and a small drink.
My favorites are the Vienna footlong and Italian. All dogs are nicely grilled, juicy, and topped with an awesome assortment of toppings (if you're not from Chicago like me). The polish is really mediocre though.
The fries are THE best part. Burning hot fresh, and you can shake your own salt and pepper at the sit down tables.
The owner may seem mean, but he is one cool guy. One time I forgot my credit card, and he let me pay it back the next time I went. I also phone in orders all the time now that I don't have a break between class and work.
He only accepts VISA or MasterCard. And even then, there is a 25 cent charge.
P.S. Ask for extra sport peppers!
