The Restaurant Miniature Buffet (or RMB) is a British Railways Mark 1 railway coach. It is a Tourist Standard Open (TSO) coach with two full seating bays next to the centre transverse vestibule removed and replaced with a buffet counter and customers standing space, and one bay on one side (same side as the buffet counter) removed and replaced with a store cupboard on the other side of the centre vestibule. They were built in five lots from 1957 to 1962.

Quite a few still operate on the national network on Railtours, but not on service trains. A lot have made it into railway preservation and are used by many heritage railways in the UK.
