I used to work near Hapjeong and came here all the time. It's the first place that comes to mind when I think of Thai food. This time I went to Saeng Augustine, a great lunch spot by Hapjeong Station. Come to think of it, I had never been with my favorite friend, so I took them along, and sure enough, they enjoyed it a lot too ^^

What we ordered for lunch, and the prices

  • Nasi goreng ₩16,000
  • King prawn pad thai ₩19,000

I ordered my usual king prawn pad thai, of course!! My friend ordered nasi goreng, a spicy, salty Indonesian fried rice ^^

Both dishes are generous in portion and beautifully plated ^^

How does the king prawn pad thai taste?

The king prawn pad thai (₩19,000) is a sweet-and-salty Thai stir-fried noodle dish with strong umami, and it's number one in my heart. Let's start with the king prawn pad thai.

It's Thailand's signature stir-fried noodle dish. The first taste is sweet and soft, and right after comes the fruity, tangy zing of tamarind sauce along with the deep umami and saltiness of fish sauce.

Bean sprouts, garlic chives and crushed peanuts served with the king prawn pad thai

It's sweet and salty with amazing umami, and I love it as it is, but if you squeeze lemon juice over it and mix in plenty of bean sprouts, garlic chives, chili powder and crushed peanuts, the texture and flavor of one bowl are pure art.

There are four big shrimp inside, and a king prawn on top too, so it looks fantastic!!

The heat of the chili powder and the nuttiness of the peanuts join the chewy noodles, and the fresh scent of the lemon makes the whole dish brighter and lighter. Still my number one!!

How does the nasi goreng taste?

The nasi goreng (₩16,000) is Indonesian-style fried rice topped with seafood and a soft-boiled egg, with a rich sweet-salty sauce and a sharp kick of spice. Nasi goreng, Indonesia's signature fried rice, is somehow familiar yet exotic, with a deep, rich flavor.

It's full of seafood and topped with a soft-boiled egg, so it's nutritious too!! Mix it all together and the richness of the yolk gently wraps the sweet-salty sauce, making it even nuttier and smoother.

Once you take a spoonful of rice, a heavy, caramel-like sweetness, much thicker and richer than regular soy sauce, spreads through your mouth. Then comes the saltiness, along with a deep, weighty umami of the sea, a bold flavor.

A subtle heat and a clean, sharp spiciness that cuts through the oiliness, plus a pungent, nutty flavor coated on every grain of rice. The depth of flavor was excellent.

Can you get a refill of the radish pickles?

I got a refill of the radish pickles (mu-pickle) served on the side. They're so refreshing and go so well with the meals that I refilled them and finished them in no time ^^
