A restaurant in central London that looks to provide obsequious, over-bearing service and second rate food at prices that only expense account carrying bankers can afford.
A wankbot is a person who is so eager to wank off himself and others around him that people refer to him as a wankbot because it's so mechanical and androidlike now.
A wankbot usually has really weird tendencies like goosestepping round rooms naked just to show off his penis and hope that others will drool over it.
