About
A modern, creative take on the traditional steakhouse, KO Prime at the Nine Zero Hotel blends an innovative menu and a luxurious dining room for one of the city’s most talked about steakhouses. Consulting chef Ken Oringer has put together an impeccably-sourced menu featuring the finest meats and outstanding seafood, complemented by not-so-standard side dishes.
Guests, in both the bar and the dining room, can lean back on cowhide cushions and enjoy the glamorous décor, which features inviting banquettes and exotic table runners all in warm, welcoming shades of chocolate browns and deep reds.
