Grind is opening its first transport hub site this autumn as part of its agreement with SSP.
The coffee and cocktail group announced late last year that it was partnering with the travel caterer to open its café-bars in airports and train stations across the UK and Europe, the first of which will be opening at London Bridge station.
The group also plans to launch another London travel hub venue this year and three more over the next three years, with a pipeline of additional locations under discussion.
Founded in Shoreditch in 2011, there are five Grind café-bars, four restaurants, a recording studio and a coffee roastery in London.
The new opening is part of a raft of new units launching at the station this year, which will also include an M&S Simply Food, a Starbucks store and SSP's new food, news and wine concept called Urban Express.
Simon Smith, chief executive of SSP UK and Ireland, said: "We are delighted to be opening these four new brands at London Bridge and to be part of the investment in this exciting new development project. These innovative brands have been carefully selected to complement the offer at the station and meet the aspirations of Network Rail and its customers."
