Koffee Mameya is less a café than a coffee laboratory, a minimalist wooden box where baristas guide you through a personal tasting rather than hand you a menu. Prices sit above average — a cup of Koffee Aug Gisha runs around ¥2,300 — and every choice is made for you after you describe what you like. Even non-experts find the flavours dense and complex, and if you love filter coffee done with obsessive care, this is one of the finest rooms in the city to drink it. No seats, no chatter, just intense cups in a hushed space.
