Mr Gill, who built the Ashoka chain of Indian restaurants, plans to open Slumdog at 410 Sauchiehall Street in October. He revealed he may open Slumdog restaurants in other UK cities if the Glasgow launch proves successful.

The millionaire had exited the Glasgow curry scene four years ago when he sold Harlequin Restaurants, the parent group of Ashoka, to long-time business associate Sanjay Majhu for £8m.

Mr Gill emphasised that he had never intended to return to this arena.

However, the concept of Slumdog came to him when he was asked to do a television programme on what people were eating in the back streets of India, to be broadcast ahead of the forthcoming small-screen premiere of director Danny Boyle’s Slumdog Millionaire.

Although this television programme never came to fruition, it put the Slumdog restaurant concept in the mind of Mr Gill.

The man who became known as the curry king with his previous venture is keeping the precise details of his new venture under wraps.

However, he did reveal that it would be based on entertainment. He added that there would be only one sitting per night, and that he did not want to fill the restaurant three or four times every evening as he had in his Harlequin days.

Mr Gill also indicated that there would be a big focus on decoration and design. He has spent a week in Rajasthan buying up wall coverings, fabrics, and cutlery, from old palaces and houses, for Slumdog.

The entrepreneur, who has been engaged in a wide range of charitable work from raising money for the Prince & Princess of Wales Hospice in Glasgow to funding mobile surgeries and cataract operations in India, refuted any notion that he was making money out of poverty as a result of using the Slumdog name.

Mr Gill also revealed that he has been looking at using the Slumdog restaurant as a platform for charitable giving.

He said of the Slumdog brand: “I don’t believe in making money out of poverty. It is a name at the end of the day. The film has made money. I don’t think it is exploitation in any sense. I don’t think anyone is getting exploited here. It is a word which is now in the dictionary. It is a word which, in a sense, I think could be perceived as quite a cool word.”

“Obviously, I gave that (Slumdog name) some thought. Personally, I thought there was nothing wrong with it. That is why I decided to use it.”

He added: “I see the whole concept, even the decor, the design, it is actually Bollywood seen through the eyes of Danny Boyle. The whole word (Slumdog) is much bigger than just the focus on poverty. In the movie, they do show the poverty. There is more to it than just the poverty angle.”

Highlighting his intention to give to charity from the new restaurant, he said: “I have given a lot of thought about linking what happens in the restaurant to giving back. I want to use this as some sort of base on which I can give back...I hope to do that - to be able to use it to benefit charities not just back in India but (also) locally.”

Mr Gill has bought the premises for Slumdog from pubs chain Mitchells & Butlers, which had operated it as the Sauchiehaugh.

The premises at 410 Sauchiehall Street were, back in the 1990s, home to trendy pub Maxaluna.

Mr Gill quipped of Maxaluna: “It used to be the in-place. It was one of those places that knocked me back and I couldn’t get in. Now I have got the keys.”

A ship carrying the wood-panelling, fabrics, tiles and cutlery which were bought by Mr Gill in Rajasthan is due in Grangemouth on September 7.

Mr Gill joked that the fit-out of Slumdog should be completed by the first week in October “depending if my container arrives from India on time - it doesn’t get pirated”.

The entrepreneur, who has starred in “The Secret Millionaire” television series, arrived in Glasgow from the Punjab in 1964. Before bringing a fresh curry experience to many people in and around Glasgow with Ashoka and Harlequin, he served as an apprentice on the Clyde at Yarrow Shipbuilders.
