This is the largest amount ever raised on crowdfunding platform Crowdcube.
The brand extended its initial fundraising deadline at the beginning of August after seeing a £250,000 surge of investment in its last week. By that time it had already exceeded its initial target of £1m.
The mini-bond campaign attracted 749 investors, who will get 8 per cent gross interest per year over a four-year term.
The average amount invested was approximately £2,900, with the largest investment at £50,000.
While 82 per cent of investors live in London and the South East, Cornwall and Scotland were also represented.
Women made up 22 per cent of the number, investing £500,000 between them.
Other investor benefits included two free burrito vouchers and a VIP bondholder party to the first 100 investors.
The 102 people that invested £10,000 or more will receive Chilango Black Cards entitling them to a free meal per week for the duration of the bond.
The funds raised will help open Chilango’s next three venues, including Camden High Street and Soho.
Speaking to BigHospitality earlier this month, co-founder Eric Partaker explained that any leftover funds would be used towards further openings in 2015.
He added that the company’s first mini-bond experience had been ‘sensational’.
