Wipe the bar top constantly. Between every drink. Every spill. Every condensation ring. The black walnut bar top is the most photographed surface in the room.
Coasters under every drink. Place mats under every plate. Never let a drink sit directly on the wood.
A sticky bar is a one-and-done bar. Guests leave after the first round. Lost revenue per seat: $40 to $60 per turn.
Beyond money: the bar top is the most visible marker of whether we care about the room. Sticky bar = nobody cares = nothing else matters.
