There is a quiet trepidation in the moment the shutters rise and the lights flicker on.
It stems from the weight of the expectations held by the guests who will walk through our doors today.
As the saying goes, great expectations can lead to great disappointment, and I often worry if a small oversight on our part might dim the experience we wish to provide.
Today, I want to reflect on five essential themes that ground my repetitive daily routine.
These are questions I ask for the sake of my business, and ultimately, for the sake of life itself.
One. What was today’s revenue? And the cost?
(Numbers are the language of tomorrow)
I have never been particularly gifted with numbers.
To be honest, I find spreadsheets quite daunting.
When my mind feels cluttered, I tend to postpone the administrative tasks that follow a busy day.
However, I know that there is no language more honest than numbers.
Revenue and cost are today’s results, but they are also the rhythm of inhalation and exhalation that connects us to tomorrow.
Understanding the meaning behind these numbers is vital for sustainable management.
Rather than a fire that blazes briefly, I want to be a steady, enduring flame that remains by our guests' side for a long time.
Two. Will the guest who visited today return to my restaurant?
(The path from a regular guest to a true fan)
When running a restaurant, you learn the weight of trust that comes from a guest returning.
When someone who visited once brings their family, and that family later returns with their friends, I realize this place is held together by more than just food.
It is likely a certain temperature, a specific mood, or a sense of comfort that lingered in their hearts.
The place that comes to mind first when something good happens; the place where you naturally dial the reservation number for a special occasion.
I hope we are that kind of destination.
I strive for a relationship where the word "fan" feels more appropriate than simply "regular."
Three. Was my food remembered as a work of art?
(A day’s devotion served on a single plate)
I hope that the tuna I prepare is remembered as a work of art.
I believe a plate is not merely a place where food is set, but a space where the emotions of a day are held.
Recently, when serving tuna, I say, "The artwork is ready," and I give the piece a name. "Mother's Birthday," "Congratulations on the Promotion," or "Beside the CEO."
The title is born from the guest’s reason for visiting and the heart they bring with them.
If my food can become a part of a precious anniversary or a small comfort at the end of a long, weary day, then I have successfully poured my entire day into that plate.
In this way, I am a person deeply sincere about tuna. I want that sincerity to be remembered like art.
That is the identity of the food I create.
Four. Are the staff happy?
(On the people we live our lives with)
I rarely use the word "employee," nor do I emphasize rigid hierarchy.
Instead, I think of them as colleagues or family.
They are not just staff; they are musicians and team members in this Goldtuna orchestra, partners who live through each day alongside me.
I often wonder how the time we spend together will be remembered by them.
What kind of person am I becoming in their daily lives?
I ask myself again today:
"Do they take pride in being part of the Goldtuna orchestra?" If the answer is "Yes," then I have lived a decent day.
Five. Are the story and branding of Goldtuna continuing well?
(Doing the difficult but necessary work)
It is often said that a beginner makes food, an intermediate makes a story, and a master builds a brand.
But branding is never as simple as it sounds.
Branding must not be the protagonist but the support, while the guest must always remain the hero.
How do you create branding where the guest is the owner?
I study this question constantly.
I strive to write a blog entry every day and share stories on social media to keep our narrative alive.
"The Tuna Uncle"—this is more than just a nickname.
It is a comfortable title born from the closeness I share with guests, and another expression of the sincerity I wish to convey.
The performance of our "Somaek Auntie" carries a cheer that goes beyond the drink itself.
I believe these moments are forms of branding that capture the heart more powerfully than any marketing slogan.
Closing Thoughts
At Goldtuna, people come before profit, emotion before structure, and attitude before numbers.
I open the doors today holding these five questions in my heart.
And when the night falls and the day ends, I say to myself:
“Choi Yeon, you lived well today.”
