Welcome to the museum.
The hall is non-descript.
This is not the British Museum. Millions of pounds have not been spent on creating a venue which is available for corporate hire. There is a desk which is populated by a miserable-looking member of staff who will only talk to you if you demonstrate your friendship to the establishment by handing over £100 for a year's membership.
There is a cafe in one corner of the hall, it sells Hube sandwiches. The food costs more than what you would typically spend, however, your grandchildren are sure to love you a little more if you get them a wheatgrass and smoked tahini baguette.
