Tortilla, the Quilvest-backed fast-casual concept, is looking to roll out its dedicated delivery kitchen model after a successful trial.

The group converted space upstairs in its Bankside location to create a backstage kitchen that could process an extra 150 orders per hour. Early indications are that delivery sales have grown by 20% with further momentum being built.

The group which operates 41 sites in the UK and internationally, said that the decision had been taken because of the difficulties of managing busy trade in the restaurant, particularly at lunchtime and the demands of delivery.

Managing director Richard Morris said: “By embracing the changes in the market, especially that on the high street, we can increase throughput without too much compromise. As much as we tried to avoid it at the start, online delivery is here to stay and unfortunately for a lot of fast-casual brands it’s a case of adapt or die.”
