Famous Tokyo Chef Shusaku Toba Opens o/sio in Singapore! | New Tanjong Pagar Restaurant (2026)

The Culinary Evolution: Why Singapore’s Dining Scene Just Got More Intriguing

Singapore’s food landscape is no stranger to hype, but the arrival of o/sio, the Tokyo-born sibling of the wildly popular sio pasta, feels like more than just another restaurant opening. It’s a strategic move that speaks volumes about the city’s appetite for elevated dining experiences—and the risks chefs are willing to take.

From Casual to Sophisticated: The Sio Pasta Effect

Let’s start with the obvious: sio pasta has been a phenomenon. Since its debut in Raffles City, the queues have been relentless, a testament to Singaporeans’ love for affordable, high-quality pasta. But what’s fascinating is how Chef Shusaku Toba is leveraging this success to introduce o/sio, a concept that’s decidedly more upscale.

Personally, I think this is a brilliant play. Sio pasta was the gateway drug—a way to introduce Singapore to Toba’s culinary philosophy without breaking the bank. Now, with o/sio, he’s inviting diners to graduate to a more refined experience. It’s like going from a great first date to a long-term relationship.

What many people don’t realize is that o/sio isn’t just a fancier version of its sibling; it’s a completely different beast. While sio pasta is all about simplicity and accessibility, o/sio is about indulgence—charcoal-grilled steaks, wine pairings, and a menu that’s as much about the ambiance as it is about the food.

The Tanjong Pagar Takeover: A Space Reimagined

The choice of location is equally intriguing. o/sio is taking over the Tanjong Pagar space previously occupied by PST Pizzeria, which is closing after just 16 months. On the surface, this feels like a straightforward handover, but if you take a step back and think about it, it’s a bold statement about the evolving tastes of Singapore’s diners.

PST’s Neapolitan-style pizzas were a hit in Tokyo, but in Singapore, they didn’t quite stick. This raises a deeper question: Are we seeing a shift away from casual, trend-driven concepts toward something more timeless? o/sio’s focus on charcoal-grilled meats and Italian classics feels like a bet on longevity over fleeting trends.

A detail that I find especially interesting is how the new restaurant will retain some of PST’s design elements. With just four days between the closure and the opening, it’s clear that much of the wood finishes and green accents will remain. This isn’t just a cost-saving measure—it’s a subtle nod to the space’s history, a way of honoring what came before while carving out a new identity.

The Menu: A Study in Balance

Now, let’s talk food. o/sio’s menu is a masterclass in balancing familiarity and innovation. About a third of the dishes are direct imports from Tokyo, but the rest are tailored specifically for Singapore. This hybrid approach is smart—it gives locals a taste of the original while acknowledging their unique preferences.

Take the Smoked Truffle Carbonara, for example. It’s a dish that feels both indulgent and approachable, a perfect representation of what o/sio is trying to achieve. Personally, I’m curious to see how Singaporeans respond to the higher price point. Pastas start at $18.80, compared to sio pasta’s $13.80. Is this a risk? Absolutely. But it’s also a reflection of the confidence Toba has in his brand.

What this really suggests is that Singapore’s dining scene is maturing. We’re no longer just chasing the next viral dish; we’re willing to pay more for an experience that feels curated and intentional.

The Bigger Picture: What This Means for Singapore’s Food Scene

If you ask me, o/sio’s arrival is a turning point. It’s not just about another restaurant opening—it’s about the broader trends shaping the industry. We’re seeing more chefs take calculated risks, more diners demanding quality over quantity, and more spaces being reimagined to meet these expectations.

One thing that immediately stands out is how o/sio is positioning itself as a destination for evening dining. This is a smart move in a city where lunch spots dominate. By focusing on wine pairings and charcoal-grilled meats, Toba is creating a dining experience that feels special, something you’d save for a date night or a celebration.

From my perspective, this is also a reflection of Singapore’s growing status as a global culinary hub. We’re no longer just a stopover—we’re a destination where chefs like Toba can test their most ambitious ideas.

Final Thoughts: A Bold Bet on Singapore’s Palate

As someone who’s watched Singapore’s food scene evolve over the years, I’m genuinely excited to see how o/sio fares. It’s a bold move, no doubt, but it’s also a calculated one. Toba isn’t just opening a restaurant—he’s making a statement about where dining in Singapore is headed.

In my opinion, the success of o/sio will hinge on whether it can strike the right balance between accessibility and luxury. If it does, it could set a new standard for what a high-end dining experience looks like in Singapore.

So, will o/sio be the next big thing? Only time will tell. But one thing’s for sure: Singapore’s food scene just got a whole lot more interesting.
