Bradford's curry capital crown is under threat because the city is saturated with poor quality restaurants, a business adviser has warned.

Arshad Javed, organiser of the Asian Trades Link which advises Asian businesses, is urging restaurateurs to branch out into different areas of cuisine to keep diners coming back for more.

And he said far too many curry houses offered the same dishes.

His warning comes after the closure of the Koh-I-Noor restaurant, formerly Bombay Brasserie, in Westgate, Bradford.

Anu Anand, who took over the listed chapel building in October 2002, moved up from London with husband Raj and their two children with dreams of running a profitable curry house.

But today Mrs Anand said she was forced to close down after falling profits and low numbers of diners.

Last year she had to use £250,000 from her husband's property business to try to keep the restaurant afloat.

"If we had been from here we would have realised a lot sooner the restaurant was a non-starter. Now, with hindsight, there's no way I would look at setting up a new restaurant in Bradford," said Mrs Anand, who used to run a five-star hotel in New Delhi, India.

"We wanted to offer a good quality Indian restaurant but we were never more than half-full, apart from over the Christmas party period.

"We are sorry for our regulars, and we are very grateful to them and we'll miss them, but we couldn't have kept it open any longer."

She said a major problem was covering the annual £52,000 rent and £24,000 rates when their income was at best £3,000 a week before out-goings.

Mr Javed said Bradford, like all cities, should offer a diverse range of restaurants catering for all tastes to keep diners coming in.

"Every curry house offers the same thing, the same dishes, the same lay-out, and it's only the big names that are doing well," he said. "There is an over-supply and people don't want more of the same."

Mr Javed said he was keen to set up a South Asian association to look at how restaurateurs could work together to improve trade in the district.

Simon Dunn, who used to represent a number of Asian restaurants and now runs Yo Yo's caf bar in Little Germany, said the problem was there was no hospitality association in Bradford to stimulate the restaurant business.

"None of the major Asian restaurant chains have premises in the city centre and if they invested in Bradford this would encourage others to come in," he said.

"There are a lot of curry houses and the market is saturated, but there is a lack of quality. What Bradford needs is a wider choice of restaurants."

Mohammed Aslam, who runs the Aagrah restaurant group, said he did not have a restaurant in the city centre because he had ones three miles either side - in Shipley and Pudsey.

"It's not planned that way on purpose and if the right opportunity came up we would look at moving into Bradford.

"Our main concern would be splitting our clientele," he said.

"There are a lot of good curry houses here and we should be proud of the culinary skills we have in Bradford and have confidence in the city's future.
