We exclusively use ours for Zizzi, Pizza Express etc. Kids love it.
4x value on a Saturday night is great, especially when there are no discounts around on the weekend if you are paying by cash.
What would easily be a £80-100 evening ends up somewhere around £30 when using CC vouchers.
If any are due to expire soon, buy a £2.50 restaurant voucher (£10 value) and the change gets credited in your next statement, thereby extending the vouchers another 2 years. Rinse and repeat.
