Enormous demand for Guzman y Gomez shares ahead of the Mexican-themed restaurant chain’s ASX listing next week has meant some investors received just 10 per cent of the stock they wanted, sources say.

Guzman y Gomez, which flagged a $2.2 billion listing earlier this month, has already increased its initial public offer by nearly $100 million to accommodate Capital Research Global Investors, which owns stakes in Chipotle, Yum! Brands and Mediterranean food chain Cava.
