The acclaimed Tokyo restaurant “sio AOYAMA,” led by owner-chef Shusaku Toba, has incorporated BRISK STAND’s signature burger cooking technique known as “Cut & Twice-Grilled” into its course menu.
This collaboration brings together Toba’s innovative culinary philosophy and BRISK STAND’s award-winning burger craftsmanship. The special burger, featuring a unique double-grilling method that locks in meat juices, is served as part of the lunch and dinner courses starting July 21, 2026.
About the Collaboration
This unexpected partnership originated from an exchange on the social media platform X (formerly Twitter), where Chef Toba shared his idea of cutting a double cheeseburger in half and grilling the exposed surface to enhance flavor. BRISK STAND, known for pioneering this “cut and twice-grilled” technique in Japan and winner of the 2025 Japan Burger Championship, responded enthusiastically. Their shared commitment to maximizing umami through precise cooking methods led to this unique collaboration.
The “Cut & Twice-Grilled” method involves slicing the burger vertically just before serving, then grilling the cut surface on a hotplate to caramelize and crisp it, allowing the bun to absorb the flavorful meat juices. This technique creates a crispy exterior with juicy, flavorful meat inside, elevating the burger experience within the refined context of “sio AOYAMA’s” innovative course meals.
Highlights
- The collaboration combines Chef Toba’s meticulous flavor balancing and storytelling with BRISK STAND’s artisanal double-grilling technique.
- The burger features 100% domestic beef patties seasoned only with natural sea salt, additive-free whole wheat buns with Yotsuba butter, and house-made simmered onions prepared over three days.
- BRISK STAND’s “Cut & Twice-Grilled” technique locks in meat juices and crisps the burger’s cut surface for an unprecedented texture and flavor.
- The dish is served as part of “sio AOYAMA’s” lunch and dinner course menus starting July 21, 2026.
