I know it's not the loop, but, there is a man who squeezes fresh orange, lime, strawberry, and pineapple on the west side of the street on Kedzie just south of 31st Street. I generally see him around 5:30 to 6am in the parking lot of the factory south of the the former site of Washburne Trade School. I am always running late and have never stopped. A co worker stops almost daily. 8-10ounces of fresh juice of your choice is $3!!
