Observed more or less every stall prepares the same menu with some add-on to make them differ from the other. However, every stall has its own beauty and style of prep. Hygienic and skills - top notch.
Night market might fool foreigner. There is ongoing issue that the vendors overcharge to foreign tourists with bad quality of the food. I would recommend the franchise Tteobokki places (copy and paste "죠스떡볶이“ ”청년다방“ "두끼떡볶이”)
Thank you so much. You are very nice. I really want to try Korean food. I usually cook kimchi soup, and buy packaged tteobokki, soicy noodle, cinnamon pancake… at Hmart.
