OMG Carm's. I used to eat there 2/3 times per week when I worked at UIC. They were famous for the "Back to School" special that they had year round. At that point it was 2 hotdogs, fries, and a small soda for $2.00. All you had to do was walk in the door and say "I'll have a back to school". You got what you paid for. I must say that I never had their ice. Haven't thought of them in years.

Now, Mario's is famous. Their sign is also full of wonderful typos. My favorite (flavour and typo) is canaloupe.

Also right there, just down Polk street from Carm's is Fontano's, which has the best subs in the world. Hands down, the best.
