I recently moved to Chicago and Best Submarine is right near my house - luckily for me! Totally affordable, most meals (that includes a can of soda and fries) are around $6!
Fries are abundant and plentiful, and all meals seem to be made to order - everything is hot and crispy. My personal favorite is the Gyro Cheeseburger ...it's a cheeseburger with Gyro meat, so good and super cheesy!
For the amount of grease and grub you get for $6....it's a budget nuts dream.
You are going to have to trust your taste buds on this one.  The food is good, the menu is huge,  and the prices are low.  That being said,  make sure you get your food and split.  Call in an order if you can.  I had a hard time keeping a straight face when he asked  "for here or to go".  I wanted to ask  "Are you serious???".
