OSO Ristorante, a contemporary fine Italian restaurant, established in 2004 by two long-time friends, Diego Chiarini & Stephane Colleoni.  Located on the top floor of Oasia Hotel Downtown, an iconic award-winning vertical garden hotel, you will experience Italian cuisine from across the regions of Italy in an understated elegance of industrial elements and vintage décor - delightful in the day to romantic when night falls. After more than 20 years with support from their team, Diego and Stephane continue to provide the same consistent energy and devotion that has won recognition and praises from guests in Singapore and around the world. Guided by the values of the group built with the team, Oso has been through all kinds of situations in the ever-changing culinary landscape; day after day with humility, pride, sincerity, creativity and freedom.
