Groupon just launched an online discount reservations system, similar to Savored but without any pre-purchase requirement. The participating restaurants include Aquavit, Picholine, DB Bistro Moderne, and The Leopard at des Artistes.

It's interesting as this was actually launched back in March 2012. (I got a member's only invitation to Groupon Reserve to access restaurants back then, but then it seemed to fade away.) It seems this is a relaunch after Groupon bought Savored. At the time, they were offering deals for specific high end restaurants, rather than just a discount for the meal.
I do believe Groupon bought Savored last year, and from looking at the OP's link, it looks like Savored in a different skin.
<similar to Savored but without any pre-purchase requirement>
Savored does not have a pre-purchase requirement.
There appears to be absolutely no difference between this and Savored, which makes sense since Groupon owns Savored, but if they are identical I wonder what the purpose is.
