One shop that helped propel gourmet sandwiches into the spotlight is Frey & Ford, a humble MTR stall that quietly started supplying quality sandwich sets to lunch crowds just over a year ago. Stocking open-faced sandwiches that are delicate in size and light on calories, Frey & Ford will put prosciutto melon, salmon dill cream, Peking chicken, crumbed fish and many other things onto the dainty bread slices for an inspired lunch experience.
