About this space

The Loose Box offers a private space separated from the main bar via a curtain, giving you the option to join the buzzing atmosphere of the main bar or to create a private space for you and your guests.

This is the perfect space to celebrate any occasions such as an after work do, corporate event, birthday, engagement. With some great drinks packages and a wide range of cocktails on offer it will be one to remember.

With the curtain drawn our space can seat up to 30 guests and stand 40, but of course if you are expecting more guests you are welcome to keep it more open.
It is also host too many facilities to offer such as a flat screen TV, wheelchair access, disabled toilets on the main floor, terrace section.

Due to this venue being wet led only we do allow external catering to be brought into the venue, including delivery services. We will assist with external catering as best we can to make planning your event as easy as possible.

Hosted my birthday pub quiz here - perfect venue, very friendly staff, with some drinks on the house at the end, and they didn’t mind my loud hosting! We’ll definitely be making a return I’m sure. Pizzas were incredible.
