The basement boiler room at The Grand hotel is set to be transformed into a ‘modern Chinese’ restaurant and bar.

BirminghamLive can exclusively reveal that the 5,000 sq ft basement space is set to become Tattu - Birmingham’s biggest one level bar and restaurant.

The entrance to the new restaurant and bar will be found at ground floor level on Barwick Street, where diners will go down a lift into the historic boiler room which will be completely transformed.

Tattu currently has two other UK sites in Manchester and Leeds.

The flagship eatery in Manchester opened to rave reviews and is a firm favourite with the city’s celebrities.

Tony Green, chief executive of Hortons’ Estate, who own The Grand Hotel confirmed to BirminghamLive that ‘subject to securing planning permission’ Tattu should be ready to open by the end of this year.

He said: “We are currently in discussions with Tattu to bring a new bar and restaurant to Birmingham that will complement the existing retail and leisure on offer at The Grand.

Brummies can expect a spectacular interior - inspired by tattoos and body art in all its forms. And taking centre stage will be Tattu’s signature cherry blossom tree.
