Shake Shack burger for New York, cheesecake for Philadelphia- guess what represents Cheonan city? I can say it is Walnut Snack without a doubt. It is a small bite-sized soft pie with a walnut and red bean paste filling. It can be easily found near subway, bus terminal and even at street vendor during winter time. Most places bake the walnut pies fresh on site, so you can watch the whole process. One of the best things about Walnut Snack is that it still tastes really good after it cools down. That’s probably why people like to bring a little bag of these sweet snacks on long trips. If you are planning to visit someone out of town, it would be a great idea to get Walnut Snack as a gift. A small gift box, which has enough amount for 2 or 3 people is only 5,000 won (a little less than $5). Just in case you get too many and have some leftovers, keep it in the fridge and microwave them for 2 minutes. It will be as delicious as the minute you bought them!
