Sixteen kilometres (10 miles) from the gleaming glass towers of Doha, one of the richest places on the planet, sits the "Industrial Area" of small-scale workshops, factories and low-cost accommodation.
It is only a 40-minute drive south of the centre of the Qatari capital and its luxury shops, upmarket brands and expensive restaurants.
But the "Industrial Area", rarely seen by outsiders, is a different Qatar -- one which provides essential labour and materials for the country's massive and relentless expansion.
About three weeks ago the Indian brothers who own Zaiqa decided to put up a small makeshift sign offering free food to customers who cannot afford to pay.
"When I saw the board I had tears in my eyes," said one of the owners, Shadab Khan, 47, originally from New Delhi, who has lived in Qatar for 13 years.
"Even now when I talk about it, I get a lump in my throat."
The 16-seater eaterie stands on the prosaically named Street 23, sandwiched between another restaurant and a steel workshop.
Inside, on brightly coloured tablecloths, "authentic Indian cuisine from the heart of Delhi" is served 24 hours a day, seven days a week.
A fish curry costs six Qatari riyals (USD 1.65, 1.50 euros), an egg roast is three riyals and a spinach dish of Palak Paneer is 10 riyals -- for those who choose to pay.
The need for free food in Qatar is particularly acute among labourers and those working in heavy industry.
"Many labourers earn 800-1,000 riyals (USD 220-USD 275) per month. They have to send money back to home. It's expensive here so there are people who need free food," he said.
Shadab, who is a filmmaker as well as a restaurant owner, said those asking for food are mostly construction workers from countries such as India, Nepal and Bangladesh.
