What We Tried
Crispy Sweet Shrimp ($12.80++)
These tiny morsels of fried sweet shrimp had a crisp coating with an addictive savoury seasoning. These were appetising and would pair great with drinks.
Snow Crab Genovese ($26.80++)
This pasta was tossed in basil pesto and topped generously with seasoned snow crab. The fresh pesto was aromatic and appetising, complemented by the sweet umami of fresh snow crab.
Our only comment is that our plate of pasta was a tad soft, we would have preferred a more al dente bite. However, the portion size of their pastas are sizable and can be shared between two!
Smoked Truffle Carbonara ($27.80++)
This carbonara is made the traditional way with no cream: only egg, smoked pancetta and Pecorino Romano, finished with black truffle and garlic chips.
The pancetta added a rich saltiness, especially with the earthy truffle. It got a bit too salty for us after toward the end, but we enjoyed the overall robust flavours.
Seafood & Datterini ($16.80++)
A pizza topped with mixed seafood, prawns and baby octopus on Datterini tomatoes, with clam jus, lemon, garlic and chilli.
While we enjoyed the bright, juicy tomatoes and fresh seafood, we found this pizza too watery. Our pizza crust was overdone with parts that were a tad too burnt; we feedbacked this to the team.
Maple Quattro Formaggi ($16.80++)–
A four-cheese pizza with fior di latte, gorgonzola, Grana Padano and mascarpone, finished with maple syrup and black pepper. If you’re a fan of the salty-sweet combo, you’d love this!
Unlike the Seafood & Datterini, this pizza was perfectly done. The crust was crisp and puffy with a pleasant chew, acting as the perfect vessel for the cheese.
What Is the Space Like?
o/sio Singapore seats about 60 and the space is set up for everything from small meals to larger group gatherings. There’s an open kitchen with a pizza oven where you can watch the chefs prepare the pasta fresh – which can get very smokey during service.
