Crisps Only, Belfast

Irish snack-time staple, the crisp sandwich, is making a comeback thanks to an online joke turned real-life venture. That Wee Café in Belfast opened a pop-up serving only the potato chip-filled sammies after reading a viral online post. Diners at the Simply Crispy pop-up can choose from 35 different crisp flavors and three different types of bread. Although it was initially meant to end after a four-week run, a sold-out opening day may inspire the owners to keep the novelty sandwich shop going long after.
