Seven servings of pork belly between four people is a lot of meat, and it filled the whole grill. That was our order at Mongttang Saenggogi, a Korean BBQ restaurant a short walk from Seongsu Station, on a Wednesday evening in March. I work in Seongsu, and this was an after-work dinner with three coworkers. We walked in without a wait and stayed about two hours. The samgyeopsal was the reason to come, the yukhoe was average, and I’d go back.
What the name means
몽땅 (mongttang) means “all of it” or “the whole lot”, and 생고기 (saenggogi) means fresh meat that hasn’t been frozen. A line on the wall inside reads “신선함을 몽땅 담아”, roughly “packed with all the freshness”. The name also shows up in the menu: the big pork platter is called 돼지몽땅 (“the whole pig”, 750 g) and the smaller one 돼지반땅 (“half the pig”, 450 g). The branch we went to calls itself the 본점, the main branch.
The table before the meat
Before the pork arrived, the table was set with a basket of red and green lettuce, a plate of pa-chae (파채, shredded green onion in a chili dressing), a bowl of kimchi, a plate of dark seasoned greens, shredded radish in a red dressing, a bowl of whole garlic cloves, ssamjang (쌈장, the thick dipping paste for lettuce wraps), and a small bowl of light broth with white cubes and a slice of red chili. Soju and beer came to the table with the sides.
Seven servings of samgyeopsal
The grill is a round, ridged plate over the burner in the middle of the table, and we grilled everything ourselves. A small foil cup of kimchi sat at the edge of the plate and cooked there alongside the pork. The menu board lists fresh samgyeopsal at 170 g per serving, so seven servings is about 1.2 kg of pork, and it covered the entire plate in one go.
The pieces were cut thick and browned on the ridges of the plate. It was very good, and it is the reason I’d return.
Yukhoe, which was average
We also ordered the yukhoe (육회), Korean raw beef seasoned and served cold. It came on a dark stone plate over lettuce, with sesame seeds on top, a pile of white strips that looked like Korean pear on the side, and an egg yolk in a separate small dish to mix in. On the menu it is 180 g of Hanwoo (Korean native beef) for 28,000 won.
For us it was average. It was the samgyeopsal, not the yukhoe, that made the meal.
Kimchi jjigae
We added a kimchi jjigae (김치찌개), kimchi stew, to go with the meat. It is 7,000 won on the menu board. I didn’t take a photo of it, so there isn’t much more I can show you.
Mongttang Saenggogi menu in English
The prices below are from the menu board in my photos, taken on March 18, 2026, with weights per serving as printed on the board. When I checked again in September 2026, DiningCode and recent visitor posts showed some prices had gone up; I’ve updated those rows and put the March price in brackets. Rows without a note are as they were in March.

Which pork cut to pick
- Samgyeopsal (삼겹살): pork belly, the classic layered strip of meat and fat. This is what we ordered.
- Ogyeopsal (오겹살): pork belly with the skin left on. O (오) means five, for the extra layers.
- Moksal (목살): pork neck and shoulder, leaner than belly.
- Hangjeongsal (항정살): a small cut from the jowl and neck area.
- Gabrisal (가브리살): a thin strip between the loin and the neck, also called deungsim-deotsal (등심덧살) in Korean.
- Naengsam (냉삼): short for naengdong samgyeopsal, frozen pork belly sliced thin.
The menu boards are in Korean only, so the tables here should help if you want to point at something. The two platters, 돼지반땅 and 돼지몽땅, are the way to try several cuts at once.

Getting to Mongttang Saenggogi
The address is 8 Achasan-ro 7-gil, Seongdong-gu (서울 성동구 아차산로7길 8), on the first floor. Google Maps lists the same place as 37 Seongsuil-ro 8-gil (성수일로8길 37); both point to the same lot, 성수동2가 289-15, but Naver, Kakao and DiningCode use the Achasan-ro address. On the map it is about 150 m northwest of Seongsu Station on Line 2, on the Exit 1 side. Recent listings show 11:00 to 22:00 on weekdays (last order 21:30) and 11:00 to 21:30 on weekends (last order 21:00), so check Naver Map before you go.
Other Korean BBQ we’ve eaten in Seongsu
- Seokam Saengsogeum-gui: pork on a stone plate, with Chapagetti served on the same plate at the end, by Exit 1 of Seongsu Station.
- Dammion: budae jjigae and suyuk gukbap, also near Seongsu Station.
My rating is 4.5 out of 5, and it comes from the samgyeopsal. If you are in Seongsu and want a plain, pork-focused Korean BBQ dinner with coworkers or friends, this is one I’d go back to.
