What it is
Tomato & Onion (fondly nicknamed Toma-Oni), founded in Maizuru, Kyoto in 1979 and today a beloved boutique brand within the Skylark Group, is a retro American homestyle diner chain. Designed like a cozy Western country home with warm timber paneling and friendly vintage collectibles, Tomato & Onion is famous for its signature "Dangan Hamburg" (弾丸ハンバーグ - Bullet Hamburg)—a 100% coarse-ground beef patty seared over flames and served rare on a sizzling skillet with a *personal red-hot heating stone (Pellet). What makes Toma-Oni an enormous favorite among travelers is its unlimited "Black Curry Bar & Soup Bar"—featuring rich, deeply spiced Japanese black curry poured over steamed rice—and its fun DIY cotton candy machine* at the drink bar!
