Hire GGB if you are committing capital to a new restaurant, café, bar or cloud kitchen and want the investment case argued before the lease; if your venue trades well and keeps too little; if you are turning one venue into a system others can run; or if your group has outgrown one person watching every kitchen. Do not hire GGB for a menu-only or logo-only brief — those are scoped standalone at best — or if you want a consultant to obtain the licence for you: licences are decided by the authorities, and any firm that promises otherwise is selling you a sequence it does not control. If the numbers say the project should not go ahead, that is what you will be told.
