Sign up to the Las Iguanas newsletter and you will be sent an e-mail containing a free voucher for a meal on your birthday. The voucher is valid 7 days before and after the day of your birthday. It is a genuinely free meal as well with no conditions attached such as the purchase of another full price meal or drinks. The only thing excluded from the a la carte menu on my last voucher was the most expensive steak. The meals vary in price from around £9.50 - £18.50.
