Theatre bars are a maths problem disguised as a hospitality problem. You have one window — usually 17 minutes — to serve hundreds of guests, and you cannot grow the bar.
01 — The windowWhy intervals are unlike any other bar service.
Interval bars share none of the assumptions of a normal pub. The crowd arrives in one wave, leaves in one wave, and there is no second chance. The bar has to absorb a year's worth of last orders in seventeen minutes.
We weren't trying to grow the bar. We were trying to remove the queue.
— Marsha Bennett, GM, Sondheim Theatre
02 — The redemption flowPre-orders, redemption queues, and a glassware overhaul.
Pre-orders were placed when the show started. By the interval, drinks had been poured into pre-labelled trays kept at temperature. Customers walked to a redemption line — not a bar — and were out in under 90 seconds.
What changed across 11 venues.
03 — The numbersThe eight-month picture.
- +32% interval spend per ticket holder.
- 11 West End venues, one shared template.
- 0 extra bar staff hired to support it.
