o/sio, the Japanese-Italian restaurant from Tokyo chef Shusaku Toba, holds its Singapore grand opening on Wednesday 4 November 2026 at 38 Tanjong Pagar Road, with Toba there in person. Reservations are open on SevenRooms and walk-ins are welcome; pizzas run $12.80 to $18.80 and pastas start at $16.80, before GST and service charge.
What o/sio is, and how it is different from sio pasta
Shusaku Toba runs sio in Tokyo, and his team already has sio pasta at Raffles City (B1-16), a casual pasta bar with plates from $13.80. o/sio is the sister restaurant, and it is a bigger, sit-down menu: starters, pizza, pasta, steak and dessert. Its own bio calls it modern Japanese-Italian cuisine by Michelin-recognised chef Shusaku Toba.
The address is 38 Tanjong Pagar Road, Singapore 088461, a short walk from Tanjong Pagar MRT. If you are making a night of the area, our Tanjong Pagar food guide has the rest of the street.
What is on the o/sio menu and how much it costs
The menu o/sio links from its bio lists, before GST and service charge:
Pizza from $12.80 (Margherita) to $18.80 (Truffle Mushroom with smoked provola and truffle mascarpone). In between: Maple Quattro Formaggi, Diavola, and Mortadella and Pistacchio. Pasta from $16.80, up to $27.80 for the Smoked Truffle Carbonara with smoked pancetta and Pecorino Romano. There is also a Snow Crab Genovese and a Spicy Vongole. Mains: a 150-day grain-fed Angus steak at $28.80 and a Duroc pork chop at $24.80. Dessert: Basque cheesecake by the slice at $9.80, or Japanese-style pudding.
For a Toba restaurant, that is a friendly price point. Two people can share a pizza, a pasta and the cheesecake for under $60 before charges. The menu marks pork in several dishes and o/sio does not describe itself as halal.
Opening day and how to book
o/sio's grand opening is 4 November 2026, and it says Chef Toba will be in attendance. Book through the SevenRooms link in its Instagram bio, or walk in.
If you want to meet him before that, sio pasta at Raffles City is hosting Toba on Monday 2 November, 5pm to 8pm, with a Toba Special Pasta served only during the event. No reservation needed for that one.
