Zizzi

The first Zizzi restaurant opened in Chiswick in 1999. As of October 2025, the Zizzi portfolio includes 138 restaurants. About 27 in London and Greater London, as well as locations throughout the United Kingdom (and also Dublin in ROI).

On 17 July 2020, during the COVID-19 pandemic, Azzurri Group, owner of the Zizzi and ASK Italian chains, announced the closure of 75 restaurants with the loss of up to 1,200 jobs.

Strand self-harm incident

On 22 April 2007, a 35-year-old Polish man entered the Zizzi restaurant on The Strand and made his way into the kitchen, where he obtained a knife. He then used it to sever his penis in front of diners. Whilst it was initially believed that attempts to re-attach the appendage had been unsuccessful, The Guardian reported later that week that surgeons had, in fact, been able to do so, "in the first operation of its kind in the country", a procedure that was carried out at St Thomas' Hospital after police recovered the penis from the restaurant floor.

Salisbury nerve agent poisoning

The Zizzi in Salisbury was linked to the poisoning of Sergei and Yulia Skripal since the pair had dined there. Those who had eaten at the restaurant and the nearby Mill Pub on Sunday 4 or Monday 5 March 2018 were advised to take measures such as washing or wiping their personal belongings, even though the risk of harm to other diners was reported to be "low".

In the summer of 2011, Zizzi began using the Pennies service in all their restaurants to give customers the option to top up their bill with a 20p donation to charity. By March 2012, over £50,000 had been raised for charity, with the majority going to long-standing charity partner The Prince's Trust. Pennies with Zizzi was crowned "Project of the Year" by the Real IT Awards in 2012, also picking up the prize for Corporate, Social and Environmental Responsibility. In 2020, Zizzi won the Lausanne Index Prize for Novel Product of the Year.
