  • Classic thick-cut fries
  • Dozens of natural wines
  • Ideal for dates and girls' nights out
  • Suitable for celebrations
  • Semi-private and private rooms available

o/sio's centerpiece is its signature meat pasta "Koku Meat," featuring thick pasta noodles coated in a rich sauce layered with demi-glace, white miso, wine, and honey, which can be enjoyed with toppings like egg, cheese, and chili oil to shift its flavors. Guests can freely mix and match charcoal grilling with Italian fare through an à la carte format, offering charcoal-grilled beef and duck infused with smoky aromas, thick-cut french fries that are crisp and savory outside, tuna tartare, and seasonal fish carpaccio. A lineup of dozens of natural wines is available, and staff recommendations tailored to your dishes and preferences are well-regarded. The slightly dim, chic, and casual interior featuring gray tiled floors and pendant lights is completely non-smoking, making it a popular destination for dates, girls' nights out, and anniversary celebrations. From start to homemade desserts like pistachio catalana, every meal ends on a high note.
