Have You Used Restaurants.com?

I'm almost positive that it's only one per. My aunt uses them if she can get really good deals. Usually, unless you're looking to spend $100, it's not worth it to me.

It's definitely not one per table as a rule.

Restaurants are allowed to put their own restrictions on how people use the cards, so it would be best to call the House of Blues to find out. We've been to a restaurant that let us (group of 8 people) use four of them at once to pay the bill, but we've also been to places that only take one per table and only during certain hours of certain days and not for certain menu items.

For the place that let us use multiples, we got four $50 for $20 each, and then I had a coupon code for 20% off, so it was about $65 for $200 in cards. I've also gotten some that after codes are less than $10 for $20 cards, just enough for a nice dinner out for us. It's a really good deal as long as the location's restrictions aren't too bad, and definitely look for additional coupon codes as well.

Ditto this. I've never used them in Orlando, but I've puchased them a few times for local restaurants in Minnesota. Every restaurant has different rules and usually if you click on the certificate it will give you details. I know a lot of them require you to spend a certain amount of money before you can use the certificate (for example, for a $25 certificate you might have to spend a minimum of $35, brining the meal cost to $10). I have yet to find one that actually covers my entire meal cost.
