This place is absolutely amazing. The combination of Thai and Korean flavors is something I never knew I needed until I tried their dishes. Personally, I can't get enough of their Korean spicy noodle with that melt-in-your-mouth pork jowl. And let's not forget the delicious Kimchi rice ball and KoThai Ceviche - so flavorful! The Grilled Hamachi Collar is another must-try item on their menu. I really love about this place is the cozy minimalistic atmosphere. It adds to the overall dining experience and makes me feel right at home. And about the staff, They are incredibly friendly and always make us feel welcome. It's the perfect combination of great food, cozy atmosphere, and amazing service. I can't recommend it enough!

Incredible. Best new restaurant in the city. The food was delicious and the staff super friendly. Can't wait to go back!! Edit: came back and added more pics

Everything was presented really nice and tasted really unique but still reflects their Korean/Thai roots! The flavors were fused beautifully and I recommend the restaurant for people that are fan of Asian food but with a tasteful twist.

It was a Tuesday night and we just finished a movie at the cinemas. Found this place online and we're so glad that we went. Didn't have to wait once we got there since they had a couple of tables open for 2. We got the beef noodle soup and korean spicy noodles. Flavors on everything were spot on. It is a little pricey, tho, but so worth it. The servers are also attentive. One of the best places we've gone to. 5 stars all around.

A must try fusion place of two distinctive Asian cuisines, Korean and Thai! The taste is super complex and authentic. When they warned me about the spicy level of their green curry, I thought to myself as a Thai person, I shouldn't have problems handling it. Turned out it's a real deal in a good way. The curry tastes just like what Thai green curry should be with the Korean twist of Kimchi and the way they wrap the cabbage around the fish. The Hamachi was grilled and seasoned perfectly. The steak was melted in the mouth. The chicken Satay is kid friendly. We will definitely go back and recommend anyone to visit this restaurant in the near future. 😀

I've been here three times in three weeks trying out the various items on their menu, and it has never disappointed. The star dishes are the noodle soups for sure, with both the beef noodle and tomyum being very different but very delicious. Chef Sung was also gracious enough to come to the front of house and answer a few questions, which was great. A very, very good addition to the Inner Sunset. I wish it success!

Absolutely delicious food and wonderful staff. The TomYum is wonderful- spicy, smooth, and full of flavor. However the price point is high for the neighborhood. The inner sunset is filled with Thai and Korean restaurants which have larger menus and lower prices. Hoping they will survive!!!!

Been here twice since they opened, my goal is to try everything on their menu :) Excellent: beef noodle soup, crispy pork, kimchi rice balls Good: mussels (with the caveat that I'm not a seafood person) Plus: large windows with great natural light during the day, chill and soft ambiance at night.

The Seabeam was pretty impressive, but beef noodle soup fell short a little bit. The chicken looks awesome but honestly did not impress as much. Overall not a bad experience.

Heard really good things about the restaurant, and went for weekend lunch. No wait. Service was attentive, and really appreciate the constant water refills! The food was delicious!!! We weren't too hungry so only ordered two items - both fish dishes. Started with the Grilled Hamachi Collar, and I can't recommend this enough. Meaty collar meat paired with a spicy-tangy breadcrumb knocked it out. It was a pretty large appetizer, with veggies too. Really set the stage for the meal. We shared the King Salmon Hak Maw. Salmon was perfectly cooked, wrapped in cabbage. Sitting in a sauce of green curry, perfect for eating with a bowl of rice. I wish there were more vegetarian options but I can't wait to come back to try more. Highly recommend!

Wow! Finally tried our new neighborhood restaurant, so glad we did. Can’t wait to go back. We started with the hamachi collar, which is amazing. Then the sea bream crudo…excellent. The shrimp ceviche was really nice, although a bit high on the spice. Last we hade the chicken toast, very good…but would have loved a few more of those pickle onions for the balance. The micro greens, especially the little baby cilantro, were a fantastic touch!

Kothai is Asian fusion restaurant (Korean/Thai) with a modern take on all dishes. We opted for the fish/seafood options which were all pretty good but not outstanding. The salmon green curry was the highlight and I would definitely order it again. The sea bream crudo with the spicy mango sauce and the hamachi collar was pretty good (collar didn’t taste the freshest though). Kimchi rice balls could have been crispier and had a strange sweetness. Mushrooms were good but the combination with coconut wasn’t anything noteworthy. The decor is pretty simple and prices are reasonable. Service was quick and friendly.

I was intrigued by the unique and concise menu at KoThai Republic, a Korean and Thai fusion restaurant in the Inner Sunset of San Francisco. The owners Sung Park and Gof Sanguanwong previously ran a food truck Spork and Stix, and this is their first brick and mortar restaurant. The weekend menu is the same for both brunch and dinner - a vibrant mix of sharable small plates and comforting rice and noodle dishes. There were dishes that you may expect from KoThai’s name, like bibimbap and tom yum noodle soup. I was also excited to see other influences, like an impressively flavorful Taiwanese beef noodle soup with a base made from scratch. Some of the more fusion dishes included kimchi fried rice balls - a nod to Italian arancini, but with kimchi, bacon, cheddar filling. The KoThai ceviche was Park’s more accessible spin on traditional gejang, or Korean marinated raw crab. This (still quite spicy) version featured cured raw shrimp, served in lettuce cups. I also liked the eye-catching presentation of the grilled hamachi collar, usually a modest side dish. Served over an addictively good bed of fish sauce-loaded bread crumbs and broccolini, the collar could be the main star. The king salmon haw mok, traditionally a Thai fish curry steamed in banana leaves, featured baek (white) kimchi wrapped salmon in a hearty bowl of green curry. And the Korean spicy noodle dish was such an enjoyable combo of bibim guksu (spicy sweet cold noodles) with Thai style grilled pork jowl. Dessert was also memorable - a cute apple pie steamed cheesecake served in a glass jar. Brown sugar crumble and lime zest topped off this crustless combo. Service was very friendly, with Sung checking in multiple times and explaining the personal inspiration and context behind many of the dishes. Definitely a neighborhood gem worth going out of your way for.

Tried: -------- - Hamachi collar: This was quite good and one of the fishier Hamachi collars I've had - Tom yum: this was fine/solid - Beef noodle soup: The soup could be stronger in taste. The beef itself was very good - Korean spicy noodle: Could've done with more noodles as it was very saucy. It leaned more peanut butter tasting. The pork was the highlight of this dish. -Thai iced tea: super creamy and thicc Seems like the proteins are done very well here. Service was nice. Ambiance is pretty casual. The tables are quite close together.

Loved the food here! I got the tom yum soup and my spouse got the beef soup. Both were really well seasoned and fresh! The space is a bit cramped and there might be a fair bit of wait time if you go in the weekends, but apart from that everything else was amazing. The head chef himself came out to check in on the diners and I thought that was a sweet touch, he has a very warm personality which shows through in his food.

I heard about this Thai/Korean fusion restaurant that opened up recently and I just had to try it. I came here to eat lunch with a friend and both of us enjoyed the meal. We did order a little bit too much and did end up having to take some food back home. The three things we ordered: - korean spicy noodles with pork - tom yum noodle soup with small rice noodles - bibimbap (not pictured) We also ordered their thai tea and their lavender coffee. For me personally, I thought the thai tea was too sweet for me. I would have preferred if there was less sugar in the tea. The korean spicy noodles were great! It had a great amount of flavor and I would order this again. The bibimbap was also delicious. The server came up to me and recommended us to eat the meat with their green sauce and that was delicious! Make sure you try their green sauce that they will provide to you. Lastly, the tom yum noodle soup tasted a little bit different from what I am used to. This wasn't my favorite dish out of the three, but it was still good.Overall, I would come back again to try their dishes. The service was great as well, and the interior was really pretty. This place is definitely a good spot for a date night or for a casual lunch or dinner with friends.

I went on a Sunday for lunch and got seated pretty quickly. The food took a bit to come out, and the portions were kind of small. I got the bibimbap and I thought it was just okay. It had mostly vegetables, it was pretty spicy, and it had very little rice. I think this place would work if you want to impress someone on a date or meeting, but for a casual lunch, it is not worth the price imo.

Every dish was yummy and unique😋 Service and ambiance were also 100/10! Hope to come back soon to try the items that sold out. Owners and staff are very hardworking and super welcoming!! One of the best restaurants in SF now

I recently visited Kothai Republic and was pleasantly surprised by how delicious the food was! From the starters of Pears and Beats and Chicken Toast to the mains of Chicken Noodle and Korean Spicy Noodle, the flavors and presentation were spot on. I highly recommend Kothai Republic for a casual dining experience, especially if you're looking for delicious Korean cuisine.
