Found another hidden gem in Sangsu area, a little Thai restaurant called Mum Aroy (뭄말로이). Having been in Korea for almost a year now, I've been eating a lot of Korean food—and it's great and all—but after a while I kinda miss other Asian food as well. And since I don't live near Itaewon, I was trying to find a good place around my area and stumbled upon this place online.
First off, I really love the vibe of the place. The decor, the music, the color of the walls, and even the utensils reminded me of my trip to Thailand and even a little bit of home. Went there with my classmates the first time so we ordered a bunch of different things to try and none of them disappointed. Everything tasted so good and they tasted pretty authentic (and by authentic I mean similar to my favorite Thai restaurants that I've visited in the past, outside Korea). And I think the fact that I've been craving it for a while kinda made the food tasted even better ;P
Here's the list of what we ordered: Tom Yum Goong (뚬얌꿍), Pad Thai (팟타이), Pad See Ew (팟시유), Green Curry (그린 커리), and Pad Kra Pao (팟카파오 무쌈) (which was SUPER HOT). And since then, I've gone back a couple of times and tried their Fried Rice (카오팟 뿌 <게살>), which was delicious as well.
If you're craving for some Thai food, I definitely recommend this place. The owners and the servers are very friendly too. And this place is actually on the same street as Grunge Cafe (see my post here), so you could get dessert there if you still have some room for dessert after your meal.
