Vietnamese restaurant in Naseong-dong, Sejong: Mekong Thai lunch combo
In short
Mekong Thai Sejong Naseong Branch is a Vietnamese and Thai restaurant on the 2nd floor of the NS Building in the Naseong-dong dining alley in Sejong. Over an early lunch the order was seafood cha gio (fried spring rolls), pho and stir-fried noodles: the pho broth tasted clean without heavy spices, while the stir-fried noodles came out sweet and salty, so the two worked well eaten in turns. For two people, Mekong Thai is best with one pho and one stir-fried noodles shared between you.

It's located on the 2nd floor of the NS Building in the Naseong-dong dining alley. Parking is easy too, so it's convenient to visit! I went for an early lunch and was able to eat at a relaxed pace.






Spacious seating for groups and QR ordering at the table
Naseong-dong favorite Mekong Thai has a spacious interior with lots of seating, so it's great for groups too. When I visited for lunch, so many office workers from nearby came in! The tables are spaced far apart, which I'd recommend even more.



If you come as a group, there are also room-like sections separated off, so it seems good for group gatherings or family meals too. At Mekong Thai in Naseong-dong, Sejong, you can order via QR code right at your seat. You can also select various options, which is convenient. We ordered a variety of dishes — cha gio, pho, and stir-fried noodles.


How the seafood cha gio and pho tasted at Mekong Thai
At Mekong Thai, the seafood cha gio (fried spring rolls) came out first and was light, making it a great appetizer. It went well with the other dishes too! ♥️

The broth was refreshing, and adding a bit of the dipping sauce made it even more delicious! The pho broth was clean yet fairly rich. It wasn't too intense or strongly spiced, so it's a flavor that's easy to enjoy without much divide in preference.

From the first spoonful of the hot broth, it had a subtle depth and savoriness that kept me coming back for more. The pho noodles were soft and easy to eat, and there was plenty of meat, making it a filling combination. In particular, since the broth isn't too heavy, it paired really well with richer dishes like the cha gio or stir-fried noodles. Even people who find strongly spiced pho difficult should be able to enjoy this without much worry! With the weather slowly turning cool these days, a hot bowl of pho really hit the spot.


Sweet, salty stir-fried noodles eaten in turns with the pho
Mekong Thai's stir-fried noodles are definitely more strongly seasoned than the pho — sweet and salty with a savory kick! Drizzling it with spicy sauce and a squeeze of lemon is delicious... I want to go back just for the stir-fried noodles.

The sauce was evenly coated on the noodles, so the flavor hit right from the first bite. The vegetables were stir-fried in as well, giving a nice crunchy texture here and there, and it had a completely different appeal from the pho. Since the pho broth is on the clean, light side, alternating it with the stir-fried noodles was a perfect combo,,!! If you eat only the stir-fried noodles, it can start to feel a bit heavy, but taking a sip of pho broth in between balanced it out nicely. If two people are visiting, ordering one pho and one stir-fried noodles to share sounds like a great combo too 😉

Every dish was clean-tasting and came out fast, which made Naseong-dong's Mekong Thai even better.

Extra bean sprouts and cilantro you can add
At Mekong Thai, you can add extra bean sprouts when ordering, so it's nice to order them ahead of time!


Overall, the dishes weren't too intense and were reliably delicious, making Mekong Thai a comfortable place for a meal.


A filling, delicious meal at this Naseong-dong spot. You can add extra cilantro too — piling it on tastes great ♥️

Worth it when you crave pho in Naseong-dong, Sejong?
I had a great meal at Mekong Thai, a pho spot in Naseong-dong! I recommend it to anyone looking for pho. The combination of clean, hot pho, sweet stir-fried noodles, and crispy cha gio worked really well together. In particular, the pho and stir-fried noodles are completely different in flavor, so if you're visiting with someone, I'd recommend ordering one of each to share! It's an easy place to visit whenever you're craving pho in Naseong-dong, and I think I'll keep coming back. If you're looking for a good pho restaurant in Naseong-dong, Sejong, give Mekong Thai a try ♥️
