Preserving a legacy...
In the heart of West Chester stands a 19th century neoclassical bank. It was a pillar of Pennsylvanian ambition for over 150 years, but its vaults eventually closed and the building laid still, yearning for a return to glory. That revival began in 2023 when owner John O’Connell, in collaboration with celebrity chef Fabio Viviani, transformed the First National Bank building into 9 Prime, the state’s grandest steakhouse, and Johnny O’s, its premier speakeasy.
The Grandeur Within...
Step through the doors of 9 Prime and be enveloped in an awe-inspiring display of excellence. Towering ceilings and mid-century furnishings meet marble bars and art-deco finishes, creating an ambiance of genial revelry.

Here, community pillars and jovial friends gather, embodying the spirit of the original 1863 bank - a hub for memorable gatherings. Big, bold, and ready to impress, 9 Prime awaits your presence
