I spend a lot of money on eating out, and so I was wondering what the best rewards credit card would be for dining. The kinds of rewards offered don't quite matter as much (though I slightly prefer points over cashback)--hotel points, miles, anything!

I've had a Citi Forward card for a few years already, it claims to give me 5x points on dining, but I'm really not sure how the Thankyou points system fares against others.
