Prezzo, the restaurant group led by Jonathan Kaye, is to pilot a new burrito concept called Chimi’s Burrito Bar on the site of its remaining Ultimate Burger unit in London’s Tottenham Court Road, M&C Report has learnt. The concept is being described as a “smaller cousin” of the group’s Chimichanga brand, with which the company is increasingly gaining transaction. If successful it could be rolled out to further sites. The group previously operated a handful of Ultimate Burger sites across the capital, but have been disposing of them or converting the units to its other existing brands over the last few years. The group recently secured its 21st Chimichanga site in Amersham, has so far opened 10 sites under the brand over the last 12 months. It has also secured a 22nd site for the brand in Ealing. Earlier this month, Kaye said that the brand had certainly come of age helped by its offer and by the fact that it coincided with the country becoming more educated when it came to Mexican food. He said: “Performance is in line with Prezzo and we are able to operate both brands in some locations without any impact on either’s trading. We will soon open a new menu for the brand and have slightly evolved the style and look of the format, with a recent example of this being at our Billericay opening.”
