Ono Hawaiian BBQ, which is celebrating its 15th anniversary this month, is basically offering its guests $15 in free food today (October 17), its anniversary date.

Here’s how it works: While supplies last, guests who spend $15 on food and drink at regular price today will receive $15 in Ono Bucks to use through the end of the year.

Plus (also while supplies last), guests who spend $15 will receive an Ono Hawaiian BBQ tote bag.

Again, this deal is for today only.

The chain is also celebrating by giving away a trip for two to Oahu, Hawaii, including a three-night hotel stay, $500, and round trip airfare.

Guests can enter the sweepstakes by clicking here.

Entrants will also have a chance to instantly win $50 in Ono Bucks or Ono Hawaiian BBQ swag.

Participants can enter the sweepstakes daily through October 31.

Inland Empire Ono Hawaiian BBQ locations include Rancho Cucamonga, Redlands, Upland, Fontana, Riverside, Apple Valley, Pomona, Chino, Moreno Valley, Mira Loma, Norco, Perris, Menifee and Hemet.
