Why Slate

Not just a venue.
A statement.

Where you take your clients says everything about how you value them. A conference room says: let's get this done. The 20th floor says: I respect your time and I want your business.

National Historic Landmark

The only event venue in Oklahoma City on the National Register of Historic Places. Once home to the Chandelle Club — one of only four rotating restaurants in the world.

Exclusive Buyout

Your event. Your floor. No shared lobbies, no hotel guests, no competing noise. Complete exclusivity from the moment your guests step off the elevator.

Above the City

Slate is not downtown. It sits above it — removed from parking struggles and urban noise. Downtown OKC has never looked more beautiful than from the 20th floor.

Designed with Intention

Velvet. Brass. Marble. A teal palette that makes the skyline pop. Every finish was chosen so your guests arrive and the atmosphere is already set.

Corporate Events

The companies that
come here don't go
back to hotel ballrooms.

Once you've hosted an event where the setting does the heavy lifting — where guests arrive and immediately feel like they were taken somewhere genuinely special — everything else feels like settling.
