After reading the other Yelp reviews, it seems like only regulars like the place while those who went out of their way to come here didn't. Honestly, I too wouldn't drive here from the suburbs just for their food, but if you're on the UIC campus and you want food quickly without walking far, then Carm's it is.
The owner is mostly at the register (old lady) and she always recognizes me even though I don't come as often anymore. There were a couple times I didn't have cash, and she gave me the food and said pay her later. Now, I always get the Fish sandwich (with giardiniera) and it tastes really good! I love it. I don't get anything else besides that, but my UIC buddies never complained about their other food. However, I gave a minus one star because the fries aren't that great. They don't taste horrible, but you have to dip it in ketchup to eat it (like I can eat McDonalds fries without Ketchup but not these).
Also, I don't think this place is really made for others besides UIC students, you can't park outside the restaurant because it's all zone parking (you need a residential sticker). So you would have to park on Taylor street and walk here. Also, this place is surrounded by Apartments, so it stands alone (I guess they were trying to be as close as possible to UIC). There aren't tables and chairs inside, they have those high rise wall tables with stools. They do have some tables and chairs outside though.
