Historical version 3 of Everyman Hampstead
Not your standard cinema! For a start, you get sofas and armchairs to sit in, and there's waiter service to your seat. They also offer screenings specifically for parents and “screaming babies” — no entry unless accompanied by someone under the age of 12 months...
Looks very interesting, and also not ridiculously overpriced; tickets start at £10 (or £7.50 for the parent/baby sessions).
