This small but inviting chain restaurant specialises in sweet and savoury porridge (juk) that can be eaten day or night. There's a well-presented English menu, though the staff's English is limited. Try bulgogi octopus porridge, shrimp porridge, tuna and vegetable porridge or, if you want something sweet, aim for red bean or sweet pumpkin porridge. Portions are ample.
You can find it on the road just to the west of Dunkin Donuts on Cheokju-ro.
