MOTHER'S Day is the time to give mothers a special treat, and what could be more special than a drawing from her child? Visitors to Harry Ramsden's Wan Chai restaurant on Mother's Day (this Sunday) are in for a visual treat. Children will be supplied with pencils provided by Caran d'Ache and encouraged to draw a pretty picture of their mums. When the composition is complete, the proud mothers will be photographed for posterity with their family. A winning drawing will be selected at the end of the day by representatives from Harry Ramsden's and Caran d'Ache. The winner will receive a free meal for four at Harry Ramsden's and a box of 36 colours from Caran d'Ache. Harry Ramsden's will be open on Mother's Day from 8 am to 11.30 am for Sunday breakfast and from 11.30 am to 11.30 pm for their traditional fish and chips menu.
