From a painting hung high on a blood-red wall, Adolf Hitler peers down on young students eating schnitzel and downing German beer in Indonesia's Nazi-themed cafe.
The SoldatenKaffee (The Soldiers' Cafe) opened its doors in the western Javanese city of Bandung in 2011, named after the popular hangout for soldiers in Germany and occupied Paris during World War II.
Much more eerie than the gas mask canisters and battle flags bearing swastikas is the more than two years' silence that has followed the cafe's grand launch.
When the cafe opened in 2011, no one voiced offence at the waiters and guests dressed as Nazi soldiers - the Holocaust is weak on the radar in Indonesia, home to the world's biggest Muslim population and where the Jewish community numbers a mere 20 people.
But a recent report about SoldatenKaffee in the English-language Jakarta Globe newspaper triggered angry responses online and prompted Bandung Deputy Mayor Ayi Vivananda to summon the owner for a meeting.
"We need to ask him first in detail what his real intentions are. But what is clear is that Bandung city will not allow anyone here inciting racial hatred," he said on Thursday.
The cafe's creator and owner, Henry Mulyana, said while it had not been his intention to bring back memories of the Holocaust, he was not surprised to be branded a "bad guy".
"I don't idolise Hitler, I simply adore the soldiers' paraphernalia," Mulyana, a Christian who likes playing with air rifles, said earlier in the week.
His collection, on display at the cafe, includes a water canteen, bayonet, goggles and a lantern, most of them bought online.
"The ones with swastikas on them are worth more," Mulyana said.
The restaurant had only ever received positive press before the recent exposure in English-language media and receives a regular stream of customers.
"We're living in Indonesia and Indonesians weren't tortured in the Holocaust, so we don't really care," said mining company employee Arya Setya, eating a plate of spaghetti at the cafe with his girlfriend.
But now that news of the cafe's existence has reached a wider audience, it has sparked outrage among Jewish communities in other parts of the world.
"The Simon Wiesenthal Center is reaching out to senior Indonesian diplomats to express on behalf of our 400,000 members and victims of the Nazi Holocaust our outrage and disgust," Rabbi Abraham Cooper, from the Los Angeles-based Jewish human rights group, said.
"We expect that all appropriate measures will be taken to close down this business celebrating a genocidal ideology that at its core denigrates people of colour and all non-Aryans," he wrote in an email to AFP.
Under Indonesian law, anyone who deliberately shows hatred towards others based on race or ethnicity can be jailed for up to five years.
But such vilification usually goes unchecked, with hardline Muslim groups carrying out violent attacks on religious minorities with near impunity in recent years.
Mulyana said his cafe has also attracted Western guests, including Germans, with one photographed on its Facebook page wearing a red swastika T-shirt along with several Indonesians in the same clothes.
He revealed he plans to set up an even bigger cafe on the resort island of Bali, which attracts throngs of foreign tourists - including Australians - each year.
"I'll certainly display Hitler's image, as well as Winston Churchill's, and paraphernalia from American and Japanese soldiers from World War II," Mulyana said.
His cafe could not contrast more deeply with attitudes in Europe, where several countries have criminalised the promotion of Nazi ideology and the denial of the Holocaust.
While Mulyana does not deny the Holocaust took place, he said making the tragedy taboo was hypocritical.
"If we want to speak up about humanity, why don't they stop wars in this world now, like in Afghanistan? War always claims so many lives," he said.
However, when contacted by AFP on Saturday, Mulyana said he had decided to close down the cafe temporarily.
Indonesia, where 90 per cent of the population of 240 million identify themselves as Muslim, does not recognise Judaism among its six official religions.
The country has no diplomatic relations with Israel and vocally advocates for the state of Palestine, although it has quietly engaged in economic and military ties with the Jewish state.
