On our last Bangkok trip, my Thai friend brought us to EmQuartier Mall and recommended a restaurant that serves good tonkotsu.
We had a table near the window where we could see Benjakitti Park. The restaurant has a stylish setting. It was almost past lunch time, so there were many empty tables.
We order two tonkotsu rice sets and a spicy black pork belly soup set.
The restaurant is famous for specializing in tonkatsu. The legendary golden fried tonkatsu was crispy and fluffy.
My meal for three came just a little near 2,000 baht. It's a bit pricey but I would return again given the quality.
