Ajummas (Korean taitais) in the know go to this hidden café in Seoul Plaza to gossip over a cup of trendy specialty coffee and a popular Korean dessert called bingsoo (빙수 or 雪花冰沙). It's made from frozen milk that's shaved into a fine, snowy powder and served with a choice of toppings. Try it with injeolmi (인절미 or 黄豆), a traditional Korean treat of ddeokk (sticky rice cakes) dusted with roasted soybean powder. It has a sweet, nutty, toasty flavor. When paired with shaved milk ice and a scoop of ice cream, it's almost like eating a frozen breakfast cereal. You can also get it topped with matcha ice cream and sweet red bean paste as well as crushed Oreos, mango, peaches and more. To find widcoffee, take the escalator to the second floor, turn left, left again, then turn right, and look for a colorful sign that says "Food Café" on your left.
