6 Reasons to Visit Gold Tuna: Seoul’s Best High-Protein Omakase 2025

When the afternoon temperature reaches 36°C, the mere thought of stepping outside can feel daunting.

I am Choi Yeon, the owner of Goldtuna.

I also share my journey and the stories of my craft through my digital journal. Over eleven years of handling the blade, I have learned a quiet truth through the work of my hands: summer is the season when tuna truly reaches its peak, and there is no more refined place to experience that flavor than here with us.

For those seeking a balance between mindful nourishment and culinary excellence, I have gathered the six charms of summer tuna and the unique secrets hidden within Goldtuna.

1. Why Summer is the Season for Tuna

From June to August, as the ocean waters warm, the fat layers of the tuna spread with delicate precision. The result is a creamy, deep 감칠맛—that savory richness—at its absolute maximum. Much like certain fish are heralded for the autumn, summer belongs to the tuna.

Consider the sweltering heat: would you rather sit before a hot grill or find sanctuary in a cool room with perfectly thawed sashimi? The choice is clear. Not only does it provide essential nourishment, but it also washes away the stress of the summer sun.

Tuna becomes a work of art.

5. Chef’s Tip for the Perfect Experience

Begin with the lean red meat (akami) paired with salt and wasabi to focus on its pure essence.

For the rich belly cuts, use a generous amount of wasabi and soy sauce—a flavor that words cannot fully describe.

A sip of a chilled highball mid-course will reset your palate for the next discovery.
