Gongdeok poke restaurant, yuzu salmon oat box to share: Why Starve

In short

Why Starve Diet Gongdeok Main Branch is a protein box restaurant on the basement level of Lottecastle President, connected directly to Exit 2 of Gongdeok Station in Mapo, Seoul. The writer ordered a Chicken Light Protein Box (8,900 won) and a Salmon Oat Protein Box (12,900 won) to go, picking oriental and yuzu sauces, and shared both at home with her mom. The boxes do not leave you stuffed but they do fill the protein gap, making Why Starve Diet an easy recommendation among Gongdeok salad and poke spots.

I went to Gongdeok Station last week, and heard there was a good poke salad place nearby, so I checked it out. I've been into healthy food lately, so protein boxes really caught my interest.

What is a protein box?

A protein box is a high-protein, low-calorie meal packed with generous protein (150g+ of meat), healthy carbs, fresh vegetables, and various grains. Whichever Why Starve Diet menu you order, it means you're getting 150g or more of meat. The name Why Starve itself apparently means: don't starve, eat.

Inside the Gongdeok branch of Why Starve Diet

Stepping inside Why Starve Diet Gongdeok Main Branch, there were a few bar-style tables and some two-person seats. Not a tiny space, and it's also comfortable for solo dining.

The menu is cutely displayed on the wall.

There's also nutrition info on one wall, checkable via barcode.

Cute stickers were on the walls too, along with country-of-origin labels — even the kiosk itself is colorful, cute, and pretty.

The two boxes ordered and the total price

Two packed protein boxes ready for takeout

Today I packed two boxes to take home and eat with mom. Chicken Light Protein Box (salad) ₩8,900, Salmon Oat Protein Box (poke) ₩12,900, totaling ₩21,800.

I chose yuzu sauce for the Salmon Oat Protein Box and oriental sauce for the Chicken Light Protein Box.

How the Chicken Light Protein Box tasted

Chicken Light Protein Box with chicken breast and vegetables

The Chicken Light Protein Box is a steady bestseller at Why Starve. It comes with 150g of chicken breast, chickpeas, lettuce, green beans, broccoli, paprika, olives, and onion flakes.

The protein box is 287kcal and 44g protein — a light way to enjoy steamed chicken breast with vegetables.

I didn't pour all the sauce on; instead I dipped the chicken in it. It was well-grilled, and tasty eaten together with the green beans, olives, and chickpeas. My mom said it was delicious.

How the Salmon Oat Protein Box tasted

Salmon Oat Protein Box with salmon steak and oats

The Salmon Oat Protein Box is a poke (Hawaiian-style raw fish bowl) menu. At 410kcal and 34g protein, it uses fresh salmon that's rich in protein but low in fat. It includes 100g salmon steak, oats, chickpeas, lettuce, green beans, broccoli, paprika, olives, and onion flakes.

For this one, I boldly poured all the yuzu sauce and mixed it into the oats. The oats had a chewy texture that I liked, and there was plenty of salmon so the portion felt satisfying.

After finishing both, I wasn't stuffed, but I felt healthy thanks to all the protein.

Final verdict on Why Starve Diet Gongdeok

Store scene with takeout and delivery orders coming in

Even outside the peak time when office workers crowd in, there were still takeout and delivery orders coming in, which shows how popular this diet restaurant really is. Next time I want to try the cauliflower protein box. For anyone looking for a good restaurant near Gongdeok Station, or a salad and poke spot in Gongdeok, I'd recommend Why Starve Diet Gongdeok.
