In short

Prepers Diet Food Sillim Main Branch (프레퍼스 다이어트 푸드 신림본점) is a two-floor salad restaurant near Exit 3 of Sillim Station in Gwanak, Seoul.

The doneness and portion of the beef chuck flap topping and the quality of the vegetables were especially satisfying.

There are so many great salad places these days! I keep gravitating to the ones with lots of topping options or generous portions~ This time I went to Prepers Diet Food (프레퍼스 다이어트) Sillim Main Branch. I'd visited another branch before and was really happy with the tasty toppings and good vegetable quality!

Since it opens at 8 AM, it's great for an early breakfast, and since it stays open late, it's also good after a night workout.

Is the Sillim Main Branch comfortable for eating alone?

Prepers Diet Food Sillim Main Branch uses both the 1st and 2nd floors, so it's really spacious, and the 2nd floor has separate sofa seats and solo seats. The 1st floor is all white, super clean, and has plenty of seats.

The 2nd floor is way bigger than the 1st!! It has sofa seats and solo seats, which I loved haha. Looking around while I ate, most of the people dining alone seemed to have come straight from a workout.

Self-serve corner at the pickup counter with spoons, forks and wet wipes

The spoons, forks, straws, wet wipes and tissues you grab when you pick up your order are all neatly set out. There are lots of staff who keep restocking them, and I liked that they quickly clear the plates at the tray return too haha.

What did I order at Prepers Sillim Main Branch, and for how much?

This time I ordered the Beef Cobb Plate Combo (₩13,900), added seasonal vegetables, sweet pumpkin and sweet potato, and got a strawberry protein milkshake too. Ordering was easy at the kiosk near the entrance on the 1st floor!

Above are photos of the Prepers Diet Food menu. The pasta salads are the most famous here, but this time I went with the Cobb salad! There are also curries and rice bowls, so it's a good place to load up on protein even if you don't want salad~

  • Fresh seasonal vegetables add-on ₩3,500
  • Sweet pumpkin, 1 scoop add-on ₩800

How was the beef topping on the Beef Cobb Plate?

Every time I come to Prepers Diet Food, I feel the beef topping is amazing! The beef topping (bu-chae-sal, a flat cut of beef) is grilled just right, piled on generously, and fills you up with plenty of protein.

Can you see that rosy pink inside? 🩷 At some other salad places, the beef topping comes out tough or badly cooked, but at Prepers it's always crispy outside, juicy inside, and so tasty! I really recommend trying it as your beef topping!!

One scoop each of sweet pumpkin and sweet potato added

Why I added sweet pumpkin and sweet potato to the Cobb salad

I added one scoop each of sweet pumpkin and sweet potato (₩800 each). When you order a pasta salad you get carbs, but with a regular Cobb salad my mouth felt a bit bored, so I added one of each. Both the sweet pumpkin and the sweet potato were nutty and sweet and really good!! 👍👍

Lemon garlic sauce served with the Beef Cobb Plate

What does the lemon garlic sauce taste like?

The lemon garlic sauce is tangy and a little sweet, so it goes well with both the vegetables and the beef. When I choose a dressing, I like a subtle flavor like this rather than a heavy one, because it doesn't overpower the ingredients.

I sprinkled on just a little, and the savory-sweet flavor was the best!! Put a bit of beef topping on the salad greens, dip it in the sauce, and it's totally delicious haha. It doesn't feel like dieting at all; it's a filling, tasty meal.

How much more do you get when you add seasonal vegetables?

Isn't the vegetable quality great too!? I added fresh seasonal vegetables (₩3,500), so the portion was a bit bigger, and there were crunchy bell peppers and broccoli too, so I got plenty of chew.

Prepers Diet Food protein milkshake

How is the protein milkshake at Prepers Sillim Main Branch?

The best thing about Prepers Diet Food is that they sell protein shakes too!!!!! There's no better place for people who work out~

Strawberry protein milkshake ordered instead of cola

When I order a set at a salad place I always end up with a zero cola, but this time I got the strawberry protein milkshake (₩4,000) instead~ It tastes like a milkshake but has lots of protein, so it's good before or after a workout. There are other flavors like plain milk, chocolate and coffee, so I'll be back for those.

If you're looking for a good salad spot or a solo-dining spot near Sillim, I recommend Prepers Diet Food: the space is pleasant and roomy, and the salad quality is great :)
