Hunting for bun cha in Naseong-dong, Sejong, on a hot day

I went to Mekong Thai Sejong Naseong Branch because I was craving bun cha (Vietnamese grilled pork with cold rice noodles). It's so hot lately that I have zero energy to cook at home!! So I'd much rather eat out!! While deciding what to eat, I wanted something fresh and light because of the heat, and bun cha came to mind!! So I looked for a place in Naseong-dong that serves bun cha and decided to try Mekong Thai!

Mekong Thai combo pho with chuck and brisket together

Mekong Thai's combo pho comes with two kinds of beef, chuck and brisket, and you can add bean sprouts, cilantro and cheongyang chili pepper (spicy Korean green chili) for free. First up, the combo pho! Having both chuck and brisket in it made it so delicious!! Bean sprouts, cilantro and cheongyang chili were free to add!!

It was savory and tasted properly like the real thing, which put me in a great mood!!

When I added bean sprouts and cilantro, they soaked up the broth and it was so good!! Thanks to the rich broth, the more vegetables went in, the more refreshing it tasted!!

With both the tender chuck and the brisket in there, it was really delicious! The two have different textures, so it felt even more generous!

Bun cha at Mekong Thai Sejong Naseong Branch comes with meat, vegetables, fried rolls and noodles, and you dip the noodles in the sauce. After that I tried the bun cha too!! It's a dipping style, like this!!

I normally love pho, but it's so hot these days that warm food is hard to eat, so being able to enjoy something this light made it perfect for summer!! Meat, vegetables, fried rolls and noodles all come together! It's a clean, refreshing taste, just right if you're looking for Vietnamese food in Naseong-dong in summer!!

Dipping bun cha noodles in the sauce

You just dunk the noodles deep in the sauce, and it's so good!! Dipped in, the sauce is mildly tangy and sweet, which really got my appetite going!! You can add vegetables or meat to taste, which is great!!

The tangy, sweet flavor is something almost anyone would enjoy!!! The bun cha pork was also full of charcoal flavor, so it was really delicious!!
