Sumi Tei Yakiniku — Restaurant in Khlong Tan Nuea Subdistrict

I usually go to Thailand once a year, I've been wanted to try authentic A5 Wagyu beef for many years now so I went on for a serious research looking for a restaurant in Bangkok that somehow serve the real A5 Japanese beef, that's when I came across to Sumi Tei. They claim to be the ONLY restaurant in Thailand that serves Imperial Wagyu A5 imported directly from Kagoshima, Japan.

I decided to get The Imperial Set (3980 Baht) which comes with 4 different parts of A5 Wagyu beef (THICK slices!) also the certificate showing the Prefecture where the Wagyu was originally bred and the cow's tag number! Very neat indeed.

The Imperial Set includes Tokusen Sirloin (เนื้อสันนอก), Tokusen Rosu (เนื้อสันกลาง), Tokusen Bara (เนื้อส่วนท้อง) and Tokusen Karubi (เนื้อส่วนซี่โครง). My favorites parts were the sirloin, rosu and karubi. Such intensely strong beef flavor, very fatty, umami, buttery and completely melt-in-your-mouth tender. For me personally, I didn't care for the sauces on the table because these marvelous wagyu already taste magnificent on it's own. I only sprinkle tiny drop of salt which enhance the umami fat flavor even more.

Overall I spent about $90 for this dinner, definitely once in a life time experience and it's totally worth it. I didn't expect to be able to eat authentic quality Wagyu beef like this in Thailand, I'm so glad I did a heavy research in order to find Sumi Tei. I highly recommend this place for anyone who wanted to try extravagant, authentic Wagyu beef without travel all the...

Ordered the A5 Imperial set and realized that the meat tasted sweet after 2-3 pieces. Server mentioned that the A5 Wagyu was served on sweet soy marinade and we have to tell them not to serve this way. I asked if this is really the case and mentioned that I do not like seasoned sauces on A5 Wagyu. They said this is really the case and refused to change remaining meat to non-marinated.

After eating and getting the bill, manager came and apologized because they made mistake and should have put two sauces on the side or asked us if we wanted the sauces at all. Offered only a 10% discount for the meal which we took. The mistake ruined the A5 set experience, which was not cheap here to start off with. I will not go back since there are better options out there without server lying to us that A5 set is served with marinade on the meat. This is your mistake and you should have comped the entire A5 set...

This is my go-to Yakiniku spot in Bangkok. I used to go to Tokyo Yakiniku, but quality there has fallen recently, while Sumi Tei is completely reliable

Great selection of Japanese and local beef, vegetables for grill, with truly excellent sauces to pair them with. Namuru and Kimchi are excellent quality. The soups are fantastic as well.

They sell shiso shochu, which is one of my favorites to mix with sencha green tea for a clean lightly sweet flavor

Order the butterhead lettuce to wrap your grilled beef in. Delicious

Embarrassingly, I sometimes go here by myself and eat what should be a dinner for 2

On another note, it’s easy to eat a near-keto meal here, plus probiotics from...
