We've used it and have been pleased. The restaurant choices for us are limited, but there are a couple we frequent. Most of the ones for us are mom and pops, which are usually diamonds in the rough. THat is to say, you can find some real gems you might not have even realized were there.
For example, our favorite local pizza place is included. We needed to buy a bunch of pizza to help the family and friends on moving day. We bought a $25 certificate for 70% of $10 (so = $3) and it required a minimum purchase of $35. I had a coupon for 2 pizzas for $17.50 (good for up to 6 pizzas.) So, I bought 4 pizzas for the gang for 2 x $17.50 = $35 and $35-$25 certif = $10 + $3 cost of certif. So fed the guys for $13 (plus tax). Cheapest move I can imagine.
