Bangkok's first Korean dessert cafe is causing a stir in the middle of Siam Square. The main attracyion is bingsu, but this is no ordinary shaved ice: the fine, snow-like ground frozen milk is piled high to resemble a mountain, which you can decorate with a choice of toppings. The toast here is also made specially of tteok (rice cake). Try the cheese bingsu, topped with grated parmesan cheese and chunks of cheesecake.
