London Venues for Award Ceremony - where have you been?

[holsareacoming]

I am looking for a London Venue to hold an educational event and wondered where you have gone before and would recommend?

Depends on the size / budget etc.

QE11
Royal Festival Hall

If you can give more info. will make some additional suggestions

Barbican
Guildford Cathedral ( not London but not far )

really depends what it is for and what size / budget

Guildhall
All the Livery Companies in the city have rooms that they rent out for events.
