the discount also works at the value food courts (plus POFQ) for 20% off and also at AK for Flame tree, restaurantasaurus, and another i forget, at WPE in the marketplace and a maybe 1 or 2 other QS locations. Of course there is no tip added. If you sit down to dine and visit alot or for a long time you can get your money's worth. We sat down for dinner at Ohana for a party of 7 and it almost paid for itself in one sitting (we had wine and alcohol discounted on the check too, another perk!)
