The company, which has opened nine sites since 2011, will return to Crowdcube to support its next stage of expansion.
Grind says it has several confirmed central London openings in the pipeline, and plans for this to be its last funding drive on the platform.
The latest funding round will allow members of the public to buy shares in the company for the second time.
“We’ve got a huge amount lined up for the next eighteen months, and couldn’t be more excited to be announcing our return to the crowd, and I can’t wait to share the news of all the exciting openings we have planned on Crowdcube next week,” says David Abrahamovitch, founder and CEO of Grind.
Grind will launch its tenth site, and first restaurant in the City of London, at the Broadgate Circle scheme in April.
It also signed a deal with SSP to open in travel hubs across the capital in 2017, with a site planned for London Bridge station.
