The Thai restaurant chain’s only remaining restaurant outside of the capital was St Albans.
The chain also acquired premises in Leeds in 2016 but financial woes and recent closures cast doubt over its future. Last year the company closed its restaurants in Liverpool and Manchester after investing £3m in the branches.
The events at Busaba Eathai make for stark contrast to those at the other brand founded by Alan Yau, Wagamama, which recently announced in a statement it was “outperforming the market by 8.2%”.
Busaba Eathai said in a statement it was looking at “delivering operational excellence and memorable experiences” at its London sites.
