I found a place near Jonggak Station in Seoul where you can easily have a light meal by yourself~ I was in the restaurant street around Gwanghwamun and Jonggak Station, and had a late lunch-dinner of diet food at Wystab Diet Gwanghwamun (와이스타브 다이어트 광화문점).

What are the atmosphere and seating like at Wystab Diet Gwanghwamun?
Wystab Diet Gwanghwamun is in a basement, so it isn't a bustling kind of place. Hip music plays nonstop, which makes it a nice spot to just focus on your meal 🎶
To make eating alone easy, there's a bar-style seating area at the entrance, and inside the shop there are tables good for 1–2 people. There are also tables that suit 3–4 people.
In one corner you can browse cute goods printed with the Wystab Diet brand character. The wall covered in stylish posters was especially memorable 😉
Wystab Diet menu and how to order

You can check the Wystab Diet menu right away on the kiosk at the entrance!

Right next to the kiosk there's also a banner introducing the signature menu items, so you can see them at a glance.

You can also add toppings, sauces and drinks to customize your meal to your taste, which I liked haha

At the kiosk you can pay easily with Kakao Pay, Naver Pay, Zero Pay and Apple Pay via QR or barcode, which is convenient 👍

There's a menu board inside the shop too, so once you're in you can also pay with Toss Pay or Samsung Pay.

Still, ordering at the kiosk is the way to see big pictures of the food right away, right? ^^
What I ordered for a late lunch-dinner: beef cauliflower rice protein box

- Beef cauliflower rice protein box
- Greek yogurt
- Drink

You pick up your order at the spot marked "Pickup". The owner calls you, so stay inside the shop~
You can choose a main meat such as beef, salmon or duck. I picked beef for the first time in a while, and the healthy veggie to go with it is cauliflower.

Even one bite fills you up with carbs, protein and fat in the right balance, a complete meal! It felt like a first step toward taking care of my health ^^



The cauliflower rice on its own tasted like a harmless fried rice, and when I ate it with the meat and vegetables on top, it was fresh and mild, not strongly seasoned, and I felt healthier just eating it lol

How does the wasabi mayo sauce taste?
I think the wasabi mayo sauce is the real kick of the Wystab Diet meal~


The zesty bite went well with the meat, and with the bland vegetables it makes the flavor much more varied. Keep dipping and the lunch box will be wiped clean in no time, a little bit of magic 😏

It may look small, but with half meat and half vegetables the amount is just right, and perhaps because every nutrient is covered, it felt filling yet not heavy 🤭

How was the Greek yogurt?
Wystab's Greek yogurt was a mild, clean, pure plain flavor with a properly thick, dense texture. It was topped with honey syrup flakes, and I occasionally bit into a blueberry~ It's quite filling, so if you're a small-appetite dieter who wants something simple, the Greek yogurt alone might be enough.

I don't have a small appetite, so for me it was more of an appetizer or dessert 😋

One thing I really recommend is ordering a drink with the protein box. A sip of fizzy soda now and then zapped away my built-up thirst perfectly 🧊 Personal taste respected, though haha
Cleaning up is self-service, and tissues are at the counter
I had a tasty, healthy meal!

When you finish, take your empty lunch box to the trash bins near the counter, sort the recycling yourself, and head out. If you need tissues, go to the counter where you got your protein box and take as many as you need. ※ I didn't see tissues or cutlery near the tables.
