North Parramatta's McDelivery service is offering ''family value'' packs containing hamburgers, soft drinks, chicken nuggets and fries (with the option of side salads) between 5pm and 9pm every day.

A McDonald's spokeswoman said the trial, which includes a $4.95 delivery fee and a $25 minimum, commenced on November 27 and had so far been ''well received'' .
