The doctor, a guest who was at the club on Sunday, claimed the governess from Meghalaya was not allowed because she was wearing a jainsem, a traditional Khasi dress, and taken for a maid.
Barthakur, who is an entrepreneur and advisor to the Assam government, told IANS that they had a lunch invitation from her friend.
In a statement issued later, the club said it had apologised to the member who had hosted the lunch, while maintaining that the guests had not been asked to leave the club premises.
She told HT, "She (Lyngdoh) was part of a group of nine, and we were guests of Pam Goyal Thimmaya, one of the longest standing members of the club.
But in India, I was told to leave Delhi Golf Club as they didn't know our culture or tradition", she said. The club officials also allegedly told her that she needed to vacate the place as she looked a like a "dustbin". "I felt ashamed and angry", Tailin Lyngdoh, who was wearing a Jainsem, a traditional dress worn by the indigenous Khasi women was quoted as saying by Indian Express.
Telling her version of the story to Mail Today, Barthakur said, 'While we were seated and having a conversation, two people approached and said Tailin could not sit with us as her dress looked like that of a maid.
'I pointed out she is wearing her cultural dress, a jainsem like others in the room are in salwar kameez. but they did not pay heed to us'.
A statement issued by club Secretary Rajiv Hora said: "An item in national dailies and social media relating to the alleged mistreatment of a guest of a Delhi Golf Club member, where the club had apparently objected to the violation of the dress code by the guest has been brought to the notice of the management".
"The reservation was for 9 people, which implied besides Mrs Goyal, 8 were her invited guests for the lunch", it further read. "I wasn't ready to accept such discrimination", she added. Though she was at the lunch as an invitee, she was "humiliated", Sondhi wrote. "We left the club feeling stripped of our dignity, feeling vulnerable for being Northeasterners and looking different". She plans to take legal action against the Club officials. "I have travelled nearly all over the world and several parts of India and have had food in the best hotels and clubs. I will also take it up with Kiren Rijiju (Minister of State for Home) and Conrad Sangma (Lok Sabha member from Meghalaya)", she said. "People in London and Abu Dhabi appreciated the jainsem".
