They face Mecca, directed by an arrow scrawled on a blackboard in pink chalk.
But Naima -- she did not want to give her full name -- had just begun the Al-Fatiha when a young woman got up and hurried out of the room in Camden in the north of the British capital.
As if on cue, "Should I Stay Or Should I Go" by punk band The Clash was playing in the restaurant.
Leila Bakkioui, 25, clad in a headscarf, admitted she was reeling.
Rasekh said: "When she came out, I thought she had seen a ghost."
Bakkioui, a young mathematics teacher, had stumbled into a group of Muslims working towards a more "inclusive" Islam, where men and women pray in the same room, with women sometimes leading the prayers.
Tamsila Tauqir helped to launch the Inclusive Mosque Initiative (IMI) in November last year after she became frustrated by what she saw in mosques in Britain and the wider Muslim world.
"There is nothing in the Koran that says that women and men can't pray together or that women can't lead prayers," said Tauqir, whose long black shirt with long sleeves matches her Dr. Martens shoes, while a keffiyeh is arranged around her neck.
But Bakkioui strongly disagrees.
"What you saw is not Islam. It's corrupt," she told AFP.
"Women can't lead if there are men in the room. And they stay behind. When you pray you bend down and you don't want to think 'he is looking at my bottom'! It's the last thing you want to think about."
A few tables away, a dozen IMI members were congregating after prayers.
"I understand that people are shocked because we have been taught that men and women pray separately, but I have adapted," said Sophia, a 33-year-old French woman who works in telemarketing. She is attending the prayer group for the first time.
"A lot of people forget to focus on the essential things. They just do what everyone else does without taking the time to read the Koran," said Sophia, a tall woman who has her dark hair pulled up into a bun.
