If you have not been to the Mozilla venue before and am travelling by tube:
Leicester Square is served by the Piccadilly line and and the western branch of the Northern line. Leave the station using Exit 4 (Cranbourn Street/Covent Garden). When you get to street-level turn left into Cranbourn Street and cross to the other side of the road. Take the first turning on the right (the corner with the Pret a Manger) into St Martins Lane. Carry on down the right hand side of the street past Noël Coward Theatre, Robert Dyas, and a Starbucks. '101' is a glassy modern office building. If you get to the Duke of York's Theatre you have over shot and need to retrace your steps :)
