Sort of. The Shanghaiborn chef might not actually own California Pizza Kitchen (CPK) but he is in sole charge of both kitchen and frontof house at this Sinan Mansions39。stalwart. It’s certainly a responsibility to be the head chef, and then to have to manage the rest of the restaurant as well, the 31yearold tells Enjoy Shanghai. In hotels, for example, these jobs are strictly demarcated, so it’s a great opportunity to learn how a business operates across the board. It was a task that management back in sunny California evidently felt he was ready for, and a vote of confi dence from a pany that, to date, has opened 250 outlets in 11 countries. And for added pressure, the Shanghai branch was also CPK’s China debut. For sure it was a big step, and unlike all their other Asia operations that are franchises, they decided to manage it directly to begin with, says Simpson. Two years ago a private franchisee took over the lease, but the links to CPK headquarters are still strong, with a mainlandbased 39。brand ambassador’ on hand to ensure the business adheres to its ethos of creating innovative, hearthbaked pizzas, a slice of PR blurb that Simpson insists lives up to the hype. They are very innovative, he says. The problem with most fast food places is that they use the same sauce on every pizza and just change the toppings. Every one of our 16 pizza sauces is a unique recipe that has been formulated to plement the toppings perfectly. The largely local customer base evidently agrees and on Saturday and Sunday, at least, the place is teeming. The kidseatforfree policy at weekends is undoubtedly a big draw, as well as is the spacious secondfl oor layout overlooked by a canopy of green from Fuxing Park over the road. The pany is also focusing on increasing brand recognition and in recent years has taken part in outside events such as the regular California Week. Still, the sta are honest enough to admit that business could be better。 as good, in fact, as in CPK’s second outlet in the popular Kerry Parkside shopping mall in Pudong. Sinan Mansions has really struggled to get the number of visitors that were envisaged when it first opened, and it hasn’t been easy for any of the tenants here, adds Simpson. We’re planning a third outlet in the city in 2021, and we will probably choose a shopping mall again because of the better foot traffi
