I received my birthday voucher for the free dinner in the Zest restaurant. There was only 1 night in the entire month to attend, so we decided to arrive early to beat the rush. We arrived at 550 pm to find a queue stretching all the way back & around the corner, must've been at least 80 people already waiting. We left immediately as a free meal wasn't worth waiting that long for. Drove down to the Lone Pine Tavern instead for a great inexpensive meal. How about the "Management" consider any night Monday to Friday to use these vouchers ??
