Papa's Pizza and Grill on 4th Avenue and 44th street fell victim to changing demographics and changes in food tastes in the neighborhood. The pizzeria had been struggling for sometime and it was only a matter of time before it closed. The increasing Mexican population around it is more in tune with their own ethnic food and don't frequent pizzerias as often. With more Mexican places and Delis opening all around offering more fast food choices the pickings were slim. It remains to be seen what will replace it. 4th Avenue is a difficult location to start an eatery. It doesn't get anywhere near the foot traffic that 5th Avenue does.
