Wagamama, the noodle bar chain, which is understood to be up for sale, has appointed Simon Gregory as its new head of property. Gregory, who has 15 years of retail property experience including positions at Victoria Wine and Specsavers, will oversee the expansion of the company’s 51-strong UK portfolio and increase the efficiency of its existing restaurants. LA Fitness, the gyms group, is believed to be among a group of potential buyers of Wagamama, which last month shelved plans for a £200m IPO. MidOcean Partners and Tragus, the private-equity backed restaurant group that owns Café Rouge, Bella Italia and Strada, are also thought to be suitors for the company, which is owned by Lion Capital.
