Thanks for that - I got 10X reward cash, which (since reward cash can be converted 1:1 to Octopus rewards) is in effect a 4% rebate on spending at the restaurants. It's not enough to change my choice of where I eat, but it would cause me to change the card I pay with to HSBC if I do eat at one of those places (and remember the deal!). For me HSBC rewards always just get converted back to Octopus rewards rather than miles these days. The mileage redemption rate and fee just isn't worth it.
