London’s best off-West End theatre, Jermyn Street Theatre impacts a far bigger stage than its tiny size. Their programme resurrects forgotten gems and new works, of which the theatre is a leading light. Accessed by a narrow archway and winding stairs, the theatre was created from the basement of an old Spaghetti House — its revitalisation and cherished status is a testament to the passion and vision of the eccentric owners Penny and Howard.
