A story of persistence, flavor and belief, passed down since 1968.
Ruenpetchsuki began in 1968 as a small restaurant occupying just two shophouses on New Petchaburi Road.
For more than half a century, it has welcomed generations of guests and families while growing alongside the changing city.
Although the restaurant is much larger today, Ruenpetch’s beginning remains in the same place, on the same road where everything started.
Before opening Ruenpetchsuki, “Agong” Guo Cicai (Mr. Singporn Loetthanaphan) grew up in a horticultural trading family in Lak Ha, Ban Phaeo District, Samut Sakhon.
Later, he joined two close friends to start a business growing and selling spices, including shallots and chillies, in their hometown. Agong himself was responsible for bringing the produce to sell at Song Wat Road, which at the time was a vibrant commercial district filled with renowned old Chinese restaurants.
Although trading was his main occupation, cooking had always been one of Agong's greatest passions. Whenever there was a merit-making ceremony or an important occasion in his hometown, he would often serve as head cook, personally overseeing the food preparation.
After experiencing Bangkok's food culture and seeing the popularity of traditional Hainanese-style sukiyaki, Agong began to set his sights on opening a sukiyaki restaurant of his own.
It took more than two years of experimentation and refinement before Agong reached a taste he was satisfied with.
Every Sunday, his day off from wholesale trading, was spent selecting ingredients, experimenting with fermented soybean paste, adjusting the fermented bean curd dipping sauce, and inviting close friends to taste the results.
Many times, the response was not what he had hoped for, but disappointment never made Agong stop trying.
His determination to make the best suki in his own style continued.
After more than two years of experimenting and refining the recipes, Agong still wondered whether the taste he had worked so hard to develop was ready for a restaurant of its own.
One day, he invited the same group of friends to dine with him once again.
This time, however, he chose a different approach.
Agong placed his own suki in the bag of a restaurant that people knew well at the time. At the same time, he placed suki from that restaurant into an ordinary container. He then served both dishes without telling anyone which dish came from which restaurant. After everyone had tasted them and shared their opinions,
Agong finally received the answer he had been searching for.
That day gave Agong the confidence that what he had spent more than two years developing was ready to leave the small kitchen and become his own restaurant.
Not long afterwards, Ruenpetchsuki opened on New Petchaburi Road, beginning a journey that continues to this day.
Once he was confident in the taste, Agong began looking for a location for his first restaurant.
After observing the atmosphere along New Petchaburi Road for some time, he decided to open Ruenpetchsuki there in 1968.
The name “Ruenpetch” came from Agong’s home, which was also located on New Petchaburi Road.
Although the restaurant has been renovated many times and the city around it has changed considerably,
we have always tried to preserve the taste of traditional suki, the fermented soybean paste, and the fermented bean curd dipping sauce according to the original recipes.
From just two shophouses in 1968, Ruenpetchsuki’s journey continues alongside the growth of our family, our guests, and new branches over the decades.
The challenge was not only making food taste good.
It was helping people believe in a name they had never heard before.
From a small restaurant in 1968,
Ruenpetchsuki has gradually grown under the care of the family, generation after generation.
Each era has brought its own changes and development, from opening new branches and adding Chinese dishes to improving service and introducing technology to make dining more convenient for our guests.
What has never changed is our determination to preserve the taste and quality of the food as closely as possible to the very first day.
From a small restaurant on New Petchaburi Road to familiar flavours shared across Bangkok and its surrounding areas.
