Don't know about Hawaii, but a lot of states don't allow discounting the alcohol. Here, the discounts are just on the food portion of the bill so if they have no food, a discount might not be possible.
This is true. Several states prohibit the discounting of alcohol, however, this does not prevent a brewery/restaurant from participating in the program.
We try to encourage new participants to be as creative as the like in coming up with offers. They are not limited to "discounts" on alcohol. Offers can be made on anything from food, drink, merchandise, tours, mug clubs, special events..etc.
