Now that I'm dieting, the hardest part is finding meals that are tasty but still filling. If I only eat salad I get hungry right away, but if I eat a regular meal I worry about the diet! So this time I looked for a place where I could eat healthy without giving up taste or portion size. The place I visited was Wystab Diet Gwanghwamun (와이스타브 다이어트 광화문점). It's a place I really want to recommend to office workers looking for diet meals around Gwanghwamun, City Hall and Jonggak!

Guide to the range of sauce options
You can choose from a variety of sauces

The menu lineup suits not only people who want to eat well while dieting but also those managing their diet while working out. What I especially liked is that it's not just salads packed with nothing but vegetables — there are menus that take carbs, protein and fat (the carb-protein-fat balance) into account, so you can have a filling meal.

Who I'd recommend it to!

  • Dieters looking for tasty health food
  • People who don't get full on small-portion diet meals
  • People who want plenty of protein while working out
  • Anyone looking for a healthy, filling meal
  • Gym-goers bulking up
  • Gym-goers managing their diet
  • Office workers around Gwanghwamun, City Hall and Jonggak looking for a simple lunch

When you're dieting, no matter how good the meal plan is, it's hard to keep up if you get hungry too fast 🥹 Wystab Diet Gwanghwamun struck me as a place where you can manage your diet without giving up taste or portion size.

Ready in 3–5 minutes after ordering!

Quick menu prep after ordering

One really great point for office workers! Every menu item at Wystab is ready about 3–5 minutes after ordering! Food coming out slowly at lunchtime is stressful, so quick prep is especially good for office workers who don't have much spare time~ It's good not only for eating in but also for taking out to eat at the office. Group orders are possible too — they said to contact them in advance — so it seems handy when several people at the office want to order diet meals together. Delivery is available as well!

It's a low-sugar menu, so it was just the right choice for me while dieting. I especially liked that it comes with cauliflower rice, so you can build a lighter meal than eating regular rice! It's disappointing when diet food comes in tiny portions, but this was really filling. And most importantly, the taste! It wasn't the bland taste typical of health food — with the oriental sauce, the savory flavor came alive and I enjoyed every bite!

How was the smoked duck tofu noodle protein box?

The other menu item was the smoked duck tofu noodle protein box! As the name suggests, it's built with carbs, protein and fat in mind, so it seemed like a good fit for people managing their diet while working out 💓 With smoked duck in it, it also looks like a good option for anyone tired of chicken-breast-heavy diet meals. Eaten with the tofu noodles, it felt like enjoying a regular noodle dish while still keeping the meal a bit lighter~

I felt Wystab Diet Gwanghwamun is a particularly decent spot for an office worker's lunch. When you work around Gwanghwamun, City Hall or Jonggak, there are times you want a healthy lunch but can't find the right place~ At times like that, being able to choose from poke, salad or a protein box to match the day's diet plan is a real plus! And since the food comes out fast, it should suit office workers with short lunch breaks too. Takeout, delivery and group orders are all possible, so it looked convenient for several people at the office to order together.

A tasty meal while dieting

I think that to keep a diet going for the long term, eating well is what matters in the end! If you eat only chicken breast and salad every day, you burn out quickly no matter how strong your willpower is 🥹 Wystab has a variety of menus — protein boxes, poke, salads — so it's good for switching things up bit by bit, and above all I liked that I didn't get that feeling of the portion being too small and hunting for something else after the meal 💓 It's a place I'd recommend to people like me who are dieting but don't want to give up taste or portion size, and to anyone who wants plenty of protein while working out! If you're looking for a healthy, filling lunch around Gwanghwamun, City Hall or Jonggak, try a meal at Wystab Diet Gwanghwamun!
