I do not mean to be a shill for this place, but I like it.
On US Route 1, just south of Guilford Road (Columbia Junction) on the Southeast side, is a trailer that sells Italian Ice. They sell both New York and New Jersey styles--one is richer than the other.
They claim homemade recipes, and it is not what you would expect for the area. There is a parking lot and tables outside. If you are around there, check it out.
