London Union, the street food market operator, is planning to launch at Woolwich Indoor Market in March.
The Jonathan Downey and Henry Dimbleby-led operator has long been associated with the site after Greenwich Council first announced the possibility in December of last year.
The site is part of the planned 740-home Spray Street development.
Downey told MCA earlier this year that he was disappointed with only one opening this year but hoped to remedy this early in 2018 with two new sites in London. He said the group had offers in on three US sites but it was unclear if any would come off.
In its most recent financial year, to 1 January 2017, the group saw turnover increase 85% to just over £9m, with EBITDA up 83% to £2.7m.
Earlier this year co-founder Henry Dimbleby said the business was likely to add longer leases into its business model as it continues to grow its estate.
He said that while the model was incredibly cash generative the plan was to build a more sustainable long-term model.
