Clapham House Group said that would raise £6.75m through a share placing to pay for acquisitions.
The group said that it had already identified possible targets of restaurant portfolios ranging from two to 15 sites.
Paul Campbell, the chief executive of Clapham House, said: "The UK restaurant sector is entering a phase where a number of companies are consolidating their operations and others may be looking to rationalise their estates.
"We believe this will lead to a number of opportunities to acquire portfolios of properties and this fundraising will put us in a strong position to proceed on one or a number of these."
The placing of 5 million shares will raise £7m, or £6.75m after expenses.
