Aruba Gastronomic Association Dine Around Program
"The list of member restaurants on this website is always changing so be sure to check for updates. Each member has provided menu highlights, a brief description, address, hours and contact information to help you make your selections."
Aruba Nights Publication
Expires Jan. 1, 2012
Discount Club Aruba (DCA)
For a fee discounts, valid until Dec 1, 2011
Unfortunately I do not think there are ever any guarantees that the coupon will be accepted, even the AGA stipulates restaurants in their plan change.
Of course there are always the coupons handed out at the airport once you exit Aruba Customs.
