When I was a kid eating my favorite comfort food, Campbell’s tomato soup with a grilled cheese sandwich, I could never have imagined anything better. But the future is here, and there is MeltKraft, a sandwich shop that has taken the grilled cheese sandwich and elevated it to a craft. The cheese is made on the premises at the Reading Terminal Market by Valley Shepherd Creamery, and the sandwich combinations are wonderfully inventive. There is no better place for a delicious and inexpensive meal in all of Center City. Foodies, don’t look the other way because it says “grilled cheese”; this is a must-try.
