Mexican fast food chain Guzman y Gomez expects annual network sales to reach $2.5 billion to $3 billion over time as it opens 30 to 40 stores a year in Australia and pushes further into overseas markets such as Singapore, Japan and the US.

Co-founder and chief executive Steven Marks said network sales were on track to rise 40 per cent to more than $400 million this year, with about 21 new stores, mostly drive through formats, augmenting same-store sales growth of around 30 per cent, while earnings before interest tax depreciation and amortisation were expected to double.
