Bored & Hungry offers original American-style smashed burgers with crispy patties, caramelized onions, and plenty of cheese sauce, along with a unique sesame oil shake, providing a calorie-rich experience with stimulating tastes.

A Korean restaurant near Ttukseom Station that offers good value for money. The Bossam Jeongshik (boiled pork slices set meal), which comes with bossam, kalguksu (knife-cut noodles), and rice, is popular. The bossam is tender without any gamey smell, and the kalguksu broth, based on beef bone, is refreshing and well-absorbed by the noodles, making it delicious.

A taco specialty restaurant located near Ttukseom Station Exit 8. Orders are placed via a kiosk, and there are bar tables perfect for solo diners. The Tandoori Chicken Taco features a harmonious blend of spicy chicken seasoning and tangy sauce, with a pleasant crunchy cabbage texture.

A great place when looking for a hearty Korean meal in Seongsu-dong, with a spacious interior that makes solo dining comfortable. The Kongnamul Gukbap (bean sprout soup with rice) comes with rice served separately and generous bean sprouts. Mixing the provided egg with seaweed flakes and broth creates a unique delicacy. The broth is refreshing and clean.

A curry specialty restaurant located a 10-minute walk from Seongsu Station Exit 3. When ordering one meal per person, rice and curry are refilled infinitely. The Assorted Curry allows you to taste various toppings such as tonkatsu (pork cutlet), sausage, chicken karaage, and king prawn tempura. The combination of turmeric rice and spicy curry is excellent.

A grilled clam specialty restaurant located a 10-minute walk from Seongsu Station Exit 3. It's so popular that there's a wait even if you do an 'open run' on weekends. The 2-person grilled clam set is very generous in portion, they kindly explain how to grill the clams, and you can later make clam soup with the clam broth.

A cafe located near Family Sonkalguksu Bossam. The coffee tastes great, and it's especially famous for its delicious canelés. There's a discount when ordering an Americano and canelé set, and canelés are beautifully packaged for gifts.

Onggundal is a famous dessert cafe in Seongsu with a really big space, featuring a garden on the first floor and a rooftop on the third, allowing visitors to spend time leisurely and take many pictures. While there are a lot of people, the space is wide, and the basic coffee taste is good, with Chamomile Lemonade being a recommended menu item.

I recommend BEP for its Yangji rice noodles with a clean, less stimulating broth that is refreshing and deeply flavored, making it a perfect hangover soup. The fried spring rolls were also delicious with a crispy, thin batter and solid filling, complementing the rice noodles well. While popular with office workers, it offers relatively cheap prices for Seongsu.
