So this is more about a dish rather than a particular place. But, if you live near a Koreatown or anywhere in Orange County, finding a place that serves that dish is a piece of cake!
So in Korean, it is phonetically pronounced pat-bing-soo. It's a cold dessert with shaved ice, a scoop of ice cream, and every topping imaginable! The classic kind that your friendly neighborhood Korean person might get has red beans in it, but also popular are fruit-based and cereal-based pat-bing-soos! Basically, anything you can put on froyo you can put in this!
