Zentralstrasse 53, 8003 Zürich, Switzerland · Japanese restaurant, Izakaya restaurant · Sihlfeld

Cozy Japanese izakaya in Wiedikon serving standout ramen and katsu with warm hospitality; book ahead and expect Swiss-level prices.

The verdict

Ooki delivers exceptional ramen and katsu with friendly, efficient service that competes with Zürich's better neighborhood restaurants. Occasional broth depth variation and a cramped dining room prevent grade A territory, though strong loyalty and cross-town appeal confirm its standing as a respected local favorite.

About this restaurant

Ooki brings a slice of Tokyo to Wiedikon, with a room that feels warm and bustling and a bar humming with slurping ramen bowls. Guests describe a friendly, fast team and a cozy, wood-and-paper aesthetic that reads authentically Japanese. One diner put it simply: "It felt like stepping into a small tavern in Japan." Reservations are wise because this place gets packed fast. The kitchen cooks classic izakaya comforts: miso and tonkotsu ramen, spicy tantanmen, crisp katsu, and shareable small plates. The approach is elevated traditional rather than experimental, with rich broths and crunchy panko textures that suit cold-weather cravings. Most praise the ramen depth and katsudon; a minority cite occasional oversalting or a broth that lacked oomph on off nights, but overall execution feels confident and consistent for Zürich standards. Families do well here thanks to a real kids menu (udon, karaage, gyoza) and straightforward flavors. If your crew prefers plain choices, there are milder soups and rice bowls; adventurous eaters can dial up spice on tantanmen. Space is tight, so strollers are easier at off-peak times.
