Bangkok does not have only China town (Yaowarat), we also have Korean town and Japanese town. I have heard people talking about the restaurants at Korean town several times, so yesterday I went there in order to see the place.
Korean town is located in the building named Sukhumvit Plaza which is located at Sukhumvit Soi 12 (on the main road). You can go there by getting off the BTS Skytrain at Asok station and walk around 10 minutes.
Honestly, I was quite disappointed with the place. The building was quite old and the gate to the second floor was under construction. The place was lifeless; I saw very few people walking around.
On the first floor, there were about 10 Korean restaurants, which is well-known for serving authentic Korean food. The menus were shown in front of the restaurants, so you can walk around and choose the one that you like.
Besides, there were 2 grocery stores selling import products from Korea such as snack, cooking sauces, rice, and kitchen utensils. While walking in the shop, I have heard the seller talked to the customers in Korean language (I guessed it was Korean; It was not English or Thai).
Anyway, some restaurants were closed. I am not sure if it is permanent, but usually the restaurants in Bangkok open on weekends. I did not go up to the second floor because it looked abandoned.
If you want to try Korean food or buy products from Korean, I recommend you to visit Korean town. But if you just want to walk around and have a window shopping, I would not recommend this place.
Have you ever been to Korean town? Have you ever eaten at the restaurants there? Share your experience with me in the comment!
