Yes Disney changed the term concierge to Club Level a while back to make it feel more exclusive. In addition to have special access to the lounge you get...
7am-10am Continental Breakfast
All Day Whole Fresh Fruit, Crudites, Dips, and Beverages
5pm-7pm Hot Item Samples from the Resorts Restaurants, Cheese Plate and Vegetables
8pm-10pm Cordials, Desserts, Beer, Wine, and other Beverages
While it is true that you are able to make dining reservations through the Itinerary Planning Office you are also able to call the 407.WDW.DINE number 180 days prior to your arrival date to make them yourself. It is sometimes easier to do these on your own in case you need to switch around some of the times.
Enjoy!
