GrabThai, the Minor International concept, has closed three of its London branches, MCA understands.

The Thai grab and go brand has closed its sites in Exchange Arcade in Bishopsgate, Leadenhall Market and Lovat Lane in Monument.

Meanwhile co-founder Chusana Prasertkul is believed to have left the business to become managing director of Greyhound Café, the Thai-founded casual dining brand, which has a site in Berners Street, Fitzrovia.

As revealed by MCA in June, GrabThai opened on 148 Fleet Street, but has yet to open another site it has in the pipeline, on 406 St John Street in Angel.

The closures leave the concept with four stores, on Old Street, One New Change, Mansion House and Fleet Street.

Prasertkul’s co-founder and husband Neetibut Vasinondha is understood to have stayed on at GrabThai as managing director.

The founders have previously told MCA they saw potential for 40 sites in London over all.

Minor operates the Suda and Patara Thai restaurant brands – and also owns majority stakes in Benihana and Corbin & King.

Prasertkul’s new employer, Thai restaurant operator Mudman, invested £3.5m in the debut UK Greyhound Café, with plans to expand it to other parts of Europe.
