Klondike has not closed the door on the possibility of bringing back Choco Tacos, the beloved frozen dessert that was collectively mourned last month when parent company Unilever announced it would discontinue the product. Choco Tacos were invented in 1983 by Alan Drazen, a Northeast Philadelphia native who had been working at Jack & Jill Ice Cream at the time. Klondike tweeted Wednesday that Choco Tacos may return in the years ahead.
