Birthday Party Venue in Spalding: Celebrate in a Cell
Looking for a birthday party venue in Spalding that feels like an occasion from the moment you arrive? Book a cell. The Cell Bar is a reservation-only, prison-themed cocktail bar and private hire event space in the original Victorian holding cells of The Sessions House, and each of its five cells holds up to 12 guests.
The Cell Bar is a reservation-only cocktail bar in Spalding, Lincolnshire, set in the holding cells on the ground floor of The Sessions House, a Grade II listed former courthouse built in 1843 on Sheep Market. It opened in July 2026 and takes private bookings seven days a week, until midnight.
It is strictly over 18s, so this one is for grown-up birthdays: a 25th, a 30th, a 40th, a 50th or any year you fancy marking with a little mischief.
Why book a cell for your birthday in Spalding?
Most birthday plans start with the same question: where can we all be together, just us? A cell answers it neatly. You book in advance, your group has its own Victorian cell, and the cell is yours for the celebration.
The setting does a lot of the work. These are the real holding cells of Spalding's old courthouse, and the prison theme runs right through, from the cocktail names to the themed glassware. Guests can even try on prison jumpsuits to get into character, which makes for a birthday photo or two.
How many guests can you bring?
Each of the five cells holds up to 12 guests, which suits a close circle of friends, a family get-together or a small surprise party. Got a question before you book? Email the team at officers@thecellbar.co.uk.
On Friday and Saturday nights there is another way in: you can book a place in a shared cell. That suits a couple or two marking a birthday together, while a private booking gives your group a cell of its own. For other private events, have a look at our guide to private hire in Spalding.
